It's for public info exchange. Joel Kendrick is a two-time IBS 600-yard Benchrest Shooter of the Year. })}); Not a lecture hall but a roundtable with a seat for you! The Tenifer process is not exclusive to Glock. Melonite Processing The MELONITE® Nitrocarburizing Process MELONITE is a thermochemical treatment for improving surface properties of metal parts. I wish this forum allowed us to publish e-mail addresses. Thread Status: Not open for further replies. Discussion in 'Rifle Country' started by razorback2003, Aug 23, 2015. Filippo. Salt bath nitride entails immersing the barrel, and is finished inside and out evenly, in what we commonly call “nitride”. There goes your accuracy. As far as I can find out, some places in Europe are still using cyanide salts. Firearms manufacturers can improve wear-resistance, erosion protection, corrosion protection and receive a uniform black finish from one process. I believe you are right there at the heart of the matter. Ever. Joined: Aug 24, 2008 Messages: 1,231. A. Both Companies produce a version of the same Walther Designed 99 pistol (Walther Tenifer over Steel and Smith amp;& Wesson Melonite over Stainless steel.) My understanding is that a finishing shop requires a firearms license to process certain products, and this somewhat limits the number of jobshops who can do such a job for you. Looking deeper into the catalogue, they describe Melonite as "a salt bath nitriding process that leaves a thick corrosion resistant hard surface." See our Line of Nitride BCG's. Just because they are the same finish doesn't mean they are applied the same way. Melonite/Nitriding exceeds the chrome lining in almost every way and hardens the metal much deeper than chrome lining. Typically this "finish" has better wear resistance than Cerakote. Also known as Melonite, Salt Bath Nitride or simply Nitride, this is a heat treating process that creates a case hardened surface by diffusing nitrogen into the metal surface. I have experienced no issues with any of them. Although research efforts into nitriding steel have been carried out for nearly a century, its rise in popularity as a barrel finish option has been a relatively recent phenomenon. A. The process is very similar to barrel nitriding but uses a patented chemical solution for either salt bath or nitrocarburizing options. SPR Barrel Bore Scope Examination at 1000 Rounds with Hard Blue. Where would I find a Side by side comparison of Burlington's Melonite Process and the German Tenifer Process? Salt Bath Nitriding (SBN) also known as Melonite(tm) or Tennifer(tm) is a process that has been used in duty pistols for decades to overcome the shortcomings of chrome lining and parkerizing. [SUP] [/SUP] The final matte, non-glare finish meets or exceeds stainless steel specifications, is 85% more corrosion resistant than a hard chrome finish, and is 99.9% salt-water corrosion resistant. razorback2003 Member. ISONITE® QPQ (per SAE AMS 2753) is a high-performance variety of salt bath nitrocarburizing process. A. I would never subject a rifle barrel to that high a temperature if the barrel were of the button rifled or hammer forged variety. If you coat bullets with moly or HBN, you will lose 50 to 100fps due to the lubricity.. My before and after FPS test with these barrel dropped 60FPS with the same load... Also, a nice thing is on the bolt, with the RC as hard as 70, it feels like glass on glass.. it really soothed it out.. See our Line of Nitride BCG's. My understanding of this salt nitriding acid bath process is that it doesn't translate well to stainless alloys, that it actually weakens their ability to withstand corrosion? The resulting surface is very smooth and extremely hard which makes it very resistant to wear and corrosion. After talking to some others, I found a place local to me.. Regards, A. I am a technical adviser for firearms industry work, and full time weapons designer and custom rifle builder, and I can assure you that the process can be used on both Button and Hammer Forged barrels. We've eased the rule from time to time, but usually quickly regretted it; it starts with an honest recommendation of a vendor, but quickly escalates to sales people posting glowing testimonials of themselves, using fictitious names and pretending to be satisfied customers :-) What happens to a Melonite pistol slide that later has to be re-blued. A. Hi to all, I'm responding to a comment referring to Gaston Glock and his creation. It does not shrink or enlarge the bore at all. Therefore he looked around and added the best technology available to do the best job. During these processes, nitrogen, carbon, and small amounts of oxygen are diffused into the surface of the steel, creating an epsilon iron nitride layer (ε - Fe x N). Instead of adding material to the bore (like Chrome lining), Nitride treats the existing steel by imbuing nitrogen into the steel itself. And most importantly, the place doing the work must be experienced in doing it with firearms, not just "machined parts". will not process actions.I think he can get them out 2-3 days. My question is related to this: Have any auto makers considered it as an alternative to paint? These processes are categorized as molten salt bath ferritic nitrocarburizing. All are actually nitrocarburizing processes that use molten salts as a source of nitrogen (+ some carbon). How salt bath nitriding works. Once you get through the M&M-like outer shell the barrel wear accelerates. Despite the naming the process is a modified form of nitriding and not carburizing. Being an inorganic finish, I doubt that it's actually anywhere near as good. } Company X might have done a bad job of applying the product. Tennifer, melonite, armornite, etc. Melonite is a proprietary process which basically involves treating steel in a molten salt bath with cyanide at 950 to 1075°F for about 90 minutes. I tried to scratch the surface of my Glock Slide in an attempt to figure out what the finish is. They have a onsite firearms consultant, metallurgist, full test lab and salt spray chambers. The finish you see on the outside looks the way it does due to the company "polishing" the finish after it is done, this is done with glass beads at 40psi to remove the oxidation from the process, while this should not effect the inside of the bore, no company would take the chance that it "might' and ruin a good barrel. I have done stainless, and chrome moly, one thing I have noticed is that the process will allow to use Chrome Moly where manufacturers would ordinarily use stainless. How salt bath nitriding works. A. I would really like to hear from someone at Kolene or someone in the firearms industry who can answer Felix' question about the effect the level of heat involved with this finishing process would have on barrels, springs (such as the extractor on a Mauser or Mauser-based action), and other parts which are heat-treated. Nitride. It is also known as Liquid/Salt Bath Ferritic Nitrocarburizing (FNC) process. UltraOx® Advanced Heat Treat Corp.'s UltraOx® treatment improves corrosion resistance properties. Thanks, Edward, but can you quote an EPA reg that says this? If they own the trade names as they claim, they are free to use them as they choose, just as Ford has been free to make a "Thunderbird" a 2-seat sports car, a More importantly - if there is any *practical* difference between the finishes? Two or three weeks later I checked it out to find several patches of rust on the slide. I sold that gun and put my Glock 34 in my trunk. It's easier to machine than steel. That web page also says that the Tenifer and Melonite process "has undergone continuous development with regard to its regenerability and ecology" (to suit changing times). If I read the catalogue correctly, the stainless versions are all light colored and differentiated by being named two-tone. Robinson arms and many many more... they know guns.. And that's whats important. A. Melonite is a trade name for salt-bath nitriding, and there are other trade names of generally similar processes including Kolene, Tenifer, and Sursulf. I assume they do this both for an even look and for additional corrosion protection. MELONITE is a thermochemical treatment for improving surface properties of metal parts. new LazyLoad(); MELONITE, and its synonymous trade-name, TUFFTRIDE (or TENIFER), are identical nitriding processes - the former term is prevalent in North America, and the latter term in the rest of the world. BENEFITS My personal Belgian made Browning High Power is fully coated. Providing consistent high quality products and services to our customers at competitive prices, while being in strict compliance with all environmental, safety and health regulations. Nitriding is a surface conversion process whereby manufacturers submerge the barrel in a nitrogen-sodium solution and heat to a high temperature, u sually between 750 and 1200 degrees. If you need a product/service, please check these Directories: Jobshops Capital Equip. The Engineers at Smith & Wesson knew that Melonite over Stainless, was a pretty advanced finish for Firearms slides. This is what the patches looked like coming out.. Thanks !!! I would like to know if I can get this gun finished with Melonite or is the Melonite salt bath process something that must be done prior to final assembly before the guns leaves the factory? My employers plant does a lot of rifle barrels for major OEM contracts so if it were a problem we would know. Our barrels can handle 20,000 rounds before replacement, as compared to 6,000-10,000 rounds on a standard M4. Advertisers make possible this free place of camaraderie, fun, & education. UltraOx® Advanced Heat Treat Corp.'s UltraOx® treatment improves corrosion resistance properties. Regards, And years of discussion on many forums, this is one of the longer running threads I found.. Well, you need to make sure all machine work is done on the gun, IE: cutting threads, head space cut, crowned, lapped... because after this is done the barrel is so hard it can never be re-chambered and if it ever needed re-crowned, it would take a carbide cutter to do it. Firearms have it pretty easy. Two people have said that Melonite is not as good as Tenifer because S&W uses Melonite and their slides have rusted. I have a barreled action for a bolt rifle that I'd like to have Melonited, but I'm concerned that doing so will compromise its properties. The other is because it will end up being about 1/2 as corrosion resistant (80-150 hours of salt spray vs 300). razorback2003 Member. elements_selector: "iframe" A discussion started in The process will add corrosion resistance, is usually known as Salt Bath hardening, and is used in Tufftride and QPQ. Melonite - QPQ (DHQN) Boriding/Boronizing (DHB) Salt Bath Nitriding (DHSN) ... Salt Bath Nitriding/Nitrocarburizing was originally created as an alternative to gas nitriding that would produce a more uniform case through surface contact between the substrate and liquid salt. I would like to reach both of you about doing some finish work... Perhaps a hint about where you work, so we could track you down by phone? If it can be refinished, what is the best way to find a reputable company that will do a good job? that have been in error. It is anecdotal, but where I've seen a barrel where a round was fired into an obstructed barrel (the shot after the squibb) - the GLOCK OEM barrel has never split - only bulged; while stainless steel aftermarket barrels (of the same dimensions) usually split. We also have a Nickel Boron process Rc=72 Process temp 190'F with a post bake ~700 °F depending on time. 416 stainless can have reduced corrosion resistance when certain types of nitriding are applied. http://savageshooters.com/SavageForum/index.php/topic,41326.0.html, http://blacknitride.com/img/friction-test.jpg. Mission Statement. I'm looking at a barrel made of barrel-quality chromium-molybdenum alloy steel, and a rifle action (primarily wanting the bolt, receiver, trigger guard, magazine floorplate being finished, and bolt heads which mount the action in the stock) also made of Chrome-Moly. I want to know if the action (DWM) can be put through this process with out harm to it. Do the Melonite properties remain in the metal or do they disappear? Yes, this will give a "super-hard" case. What might be a viable treatment for the exposed metal? The Tenifer type finish seems to have great protective properties. Okay, so if these two processes are the same, how come I've seen Smith and Wesson firearms that are Melonite treated rust/corrode, but Tenifer doesn't? Tennifer, melonite, armornite, etc. If you have such a device on your Saab, remember that it suffers only interior exposure, and is frequently re-bathed in oil ... and even then it may not be still perfect after 20 years. Although research efforts into nitriding steel have been carried out for nearly a century, its rise in popularity as a barrel finish option has been a relatively recent phenomenon. The normal temps for steel in the gun industry is from around 975 to 1100. Joel, a past 600-yard Shooter of the Year, is very knowledgeable about both shooting and the nitriding process. Smith & Wesson didn't just pull Melonite out of a hat. Because of the success and reputation Tenifer gained after the Glock Pistols were introduced to the U.S. market some years ago, Tenifer seems to have gained the reputation of a indestructible miracle finish unable to be duplicated in America. Don't want to stray too far off-topic, but Michael V. -- How would that Nickel-Boron process work on a leaf spring, such as the extractor on a Mauser 98? The hallmark of salt bath nitriding is the bath of molten salt (usually cyanide or other salts) into which parts are submerged. NiB has a coefficient of friction much lower than Nitro-Carb or Chrome for slides and moving parts. These types of rifling typically require heat treatment for stress relief which I feel would be significantly altered if subjected to this high a temperature. A. The chemicals/salts utilized for the MELONITE are different than the ones utilized for Arcor - the former process predates the latter and both are registered trademarks of … this process uses a salt-bath process, too. Q. His charge $75 a barrel plus $25.00 shipping fee ground. Consult'g, Train'g, Software Environmental Compliance. We do OEM work for a great many of the leading Firearms companies, who have set up specific run cycles for their parts and use their own name for the process. Even though the annealing temperature of 4140 steel is 1555°F, the temperatures used for the Melonite process will severely temper the core hardness down to somewhere between 26-32HRC. My experiences have shown me that a new load development will be in order. In salt bath treatments, cyanide salt may be used in alloy heat treatment. Salt bath nitriding is a case hardening process that leaves a fairly thick, corrosion resistant, hard surface. We Ultra Sonic dip clean every gun that comes in the door to make sure they are 100% clean inside and out so we have no imperfections in the nitride.". Nitriding has several trade names such as Melonite, Tenifer, QPQ, Salt Bath Nitride, and others. Nitride VS Cerakote. I know melonite is just a brand name for a particular salt bath nitride process/ product, and it works by chemically changing the makeup of the surface, as opposed to … The main difference between the Tenifer and Melonite processes is a matter of splitting hairs. A fair amount of internet searching have not helped in finding people with experience in having guns refinished with Melonite. A. Some of the things I found doing the research.. H&M was started in 1948 and has been family owned since, The do work for the large car companies, GE , NASCAR and a bunch of others listed on their page. Hi David. A. So neither process is quite the same process as it was in the past. Recommendations? Bill. } Q. I had a few long calls with the General Manager, Shade McMillen to gather info before having work done there.. new LazyLoad({ Salt Bath Nitriding Xylan Coating Phosphate Conversion. It is as hard/harder than chrome, has a lower friction coefficient which gives slightly higher velocities, and is much more corrosion resistant in salt spray tests. Q. The shared attributes of this class of this process is the introduction of nitrogen and carbon in the ferritic state of the material. We're going to find out at what point this rifle will fail and take a look at what the barrel will look like when we get done with it. The method features the transfer via diffusion of carbon and nitrogen from the molten salt to the surface of a steel part. Joel, a past 600-yard Shooter of the Year, is very knowledgeable about both shooting and the nitriding process. Fluidised bed/salt bath nitriding/nitrocarburising is a process used to improve the wear resistance, fatigue strength and, when combined with post oxidation through oxidative cooling, improved corrosion resistance on products made from steel, cast iron and sintered iron. He can give you well-informed answers to your questions. ©1995-2021 finishing.com, Inc., Pine Beach, NJ   -   About finishing.com   -  Privacy Policy My question regards the Melonite/Tenifer debate and actually is quite simple. Frank....tool and die trade. A. THEY ARE THE SAME EXACT THING! Q. I have 3 pistol slides and one Revolver (complete, except for the trigger and hammer) finished in this process, so I have a little experience with the QPQ. No rust on the slide or barrel. The difference is in the use of cyanide (I think). The facility we selected is located in the Mid West (no secret there) and let's not give Gaston Glock too much credit, the Tenifer finish has been used by the German automotive industry for years, including BMW and Mercedes.

Joined: Aug 24, 2008 Messages: 1,231. Disclaimer: It's not possible to fully diagnose a finishing problem or the hazards of an operation via these pages. Would you nitride/melonite a rifle or cerakote one? rlanier77@hotmail.com has taken over that account. Q. A cut rifled barrel of high quality chrome moly steel might make a good experiment for someone to try, however, as an experienced gun smith, I would not want to be the first to pull the trigger in an unprotected environment. It remains a popular case hardening technique because it offers: According to a graph in the referenced and linked article from Kolene, it looks like there is some small effect to a depth of about 40 microns, but the bulk of the effect pertains to the first 3 or 4 microns. Above: Toolcraft BCG with Black Nitride finish. In other words, is it (the Melonite) a permanent part of the metal. Bill, A. Hi Bill. & Install'n Chemicals & Consumables All are actually nitrocarburizing processes that use molten salts as a source of nitrogen (+ some carbon). I do not have any special inside information, but I believe that Glock will not let the supplier license the Tenifer name to any other firearms manufacturer; therefore, other firearms manufacturers are using a similar finish but from other chemical suppliers or under different tradenames. Q. A friend of mine has carried both guns concealed and his Glock 26 never rusted, but his M&P 9 compact did? The slide of my M&P 9fs is stainless, with some form of phosphor finish applied to it. It is a thermochemical diffusion process whereby nitrogen-bearing salts generate a controlled release of nitrogen at the interface of a ferrous part. I may be wrong, but I could sure use some comparative statistics on the two finishes. From what I understand - Tenifer can't be applied in the US because the EPA won't allow it. The normal temps for steel in the gun industry is from around 975 to 1100. A. The material is used for crankshafts, suspension parts and whatnot--exposed to stresses not unlike guns. In fact SAAB of Sweden once used the same process for it's cam and crankshafts. Melonite is the salt bath nitriding treatment used by S&W. A. Hi, again, cousin Michael. "popup": { But the original German formulation for the "Tenifer" carbonitriding salt bath used 60% sodium cyanide and cyanate and 40% potassium cyanide and cyanate.... That's why the EPA wouldn't let anyone do it here. A. Ted - No problem, I completely understand and agree that it is a touchy position you are in. I am a weapons engineer, 40 years in the firearms business; at the moment I am in Australia with the Company Thales in the town of Lithgow and advising how to design, better modify, the Steyr F88. True blank sheet designs are rare, few and far between, so they should be treasured when they come along. This is done through a gaseous plasma or a liquid salt-bath and there are various nitrocarburization processes depending on the technical need. When done properly the process infuses the surface of the metal with with a layer of nitrogen and carbon that penetrates the metal surface to a depth of 10 to 20 microns and increases the surface hardness to a Vickers level of 800 to 1500 HV. Wear tests and practical application repeatedly confirm the superior wear resistance of salt bath nitrocarburized parts over traditional or induction hardened or hard chrome plated surfaces. "background": "#237afc" Salt Bath Nitriding. Melonite vs Nitride. Don't expect your old load to shoot the same. A no-registration-required forum naturally draws them. Is this used in any handgun, to anyone's knowledge? It is 0.05 mm (0.0020 in) thick and produces a 64 Rockwell C hardness rating via a 500 °C (932 °F) nitride bath. I believe the Tenifer/Melonite is the resulting finish. There’s also TiAlN (Titanium Aluminum Nitride) and others. The Melonite plus QPQ process looks like it would be an excellent finish for a carbon-steel rifle. I don't know whether it is or isn't. ." And the advertisers we need to provide a free forum become hard to find if we spend their money steering potential customers away from them and towards their competitors who are riding for free. Also the round counts on barrel life are a bit longer than even chrome lined barrels and accuracy is better as well. How Google uses data when you visit this site. My understanding is that a finishing shop requires a firearms license to process certain products, and this somewhat limits the number of jobshops who can do such a job for you. Salt-bath nitriding changes the surface area molecular framework of the metal for about four-eight microns. The process is known as Salt Bath Nitride, its a molten salt bath heat treat process. The salt bath nitriding process features a few benefits over pre-existing chrome lining technology. It exhibits predictable and repeatable results in the treating of low and medium carbon steels, alloy steels, stainless and austenitic steels, tool and die steels, cast and sintered iron. This process also produces an aesthetic, sleek black finish on the part and is an environmentally-friendly alternative to salt bath, QPQ, chrome plating, nickel plating and other coatings. Also, SBN can not "chip" off like chrome or other coatings... resistance and same lubricity as black... but not as hard. It wasn't something he came upon all by himself. The process may also be used as a part of liquid Nitriding treatment. Lap the bore and scrub out the chamber good. Fabulous for bolt carrier groups, actions, and slides. Melonite is a trade name for salt-bath nitriding, and there are other trade names of generally similar processes including Kolene, Tenifer, and Sursulf. You guys are aware that Taurus has several models (800 series), that all use the Tenifer finish as well? Unlike chrome lining where the chrome is built up on the surface, nitriding converts the surface with out the risk dimensional build up causing fitment and function issues.". The processes are broken up into four main classes: gaseous, salt bath, ion or plasma, or fluidized-bed. Salt bath nitriding is far better than black oxide, but that doesn't make it better than auto paint. One is that it costs more than 4140 with no benefit. Start by running a WET patch in the bore when u get it back... "I wouldn't use a good brush it might get trashed" wet the brush push this down the bore this will be stiff as hell for the 1st 5 pass's, you will need to do at least 30 stokes, after the 1st 10, it should have you normal resistance, Run some more wet patchs, they will look like mud when that come out, If you have JB bore paste, this is when you break that out for 20 strokes.. if no JB, us can use flitz or other polish on a patch. The only difference in the "Tenifer" process and "Melonite" is the brand name. I would suggest that anyone who is interested in this process may wish to review the Kolene paper on the QPQ process at http://www.finishing.com/library/qpq/. Melonite is a form of nitriding. I suggest using a mild abrasive such as Flitz, Iosso, or JB Bore Paste on a tight fitted patch. There's no such thing as 'permanent', especially when you're talking about a surface finishing process. Both guns i have done this to get zero copper fowling, i just took my 260 in the pics to a 1200y shoot the other day and put 125 123amax @ 3250fps down the tube... no fouling.. havent cleaned it and put another 75 down, still no copper.. Tennifer is the salt bath nitriding treatment used by Glock. Jeff. Excellent sliding and running properties, as well as greater wear-resistance, are the well-known advantages of MELONITE ®-treated components. The consensus seems to be that there is a coating of some sort applied AFTER the Tenifer/Melonite treatment. are all trademarked types of nitride in use by Glock, Smith & Wesson, etc. He can give you well-informed answers to your questions.
