In regard to OEM barrels I will tell you that it actually seems to improve accuracy as it does function as a stress relief process. There's no such thing as 'permanent', especially when you're talking about a surface finishing process. Two or three weeks later I checked it out to find several patches of rust on the slide. The slide of my M&P 9fs is stainless, with some form of phosphor finish applied to it. will not process actions.I think he can get them out 2-3 days. Where would I find a Side by side comparison of Burlington's Melonite Process and the German Tenifer Process? 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. Q. It is a thermochemical diffusion process whereby nitrogen-bearing salts generate a controlled release of nitrogen at the interface of a ferrous part. It remains a popular case hardening technique because it offers: 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. Thread Status: Not open for further replies. 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. [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. He can give you well-informed answers to your questions. Remember this temperature for later. Melonite is a form of nitriding so it's really asking phosphate vs. nitrided. The Engineers at Smith & Wesson knew that Melonite over Stainless, was a pretty advanced finish for Firearms slides. Discussion in 'Rifle Country' started by razorback2003, Aug 23, 2015. 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.". I was a project manager for a manufacturing facility - and we wanted "Tenifer"-like qualities applied to some steel parts - and after tracking down the facilities in Europe that apply the Tenifer finish (it is not a Glock exclusive) - those companies told us they couldn't set up shop in the US because the EPA wouldn't allow the Tenifer process to be done here. Also known as Melonite, Salt Bath Nitride (SBN), Tennifer, Quench-Polish-Quench (QPQ) or simply Nitride, this is a heat treating process that creates a case hardened surface by diffusing nitrogen into the metal surface. Post-processing - It is important to thoroughly clean your barrel again before you resume shooting. Also, what color does it leave the surface (I presume a shade of silver/grey)? Would you nitride/melonite a rifle or cerakote one? Typical Hardness ranges from HRC 60 to HRC 70-75 on Stainless steel. Salt Bath Nitriding. Like Crazy Einar I give Gaston Glock kudos because when he put down his ideas for gun designs he didn't know anything about it ... so he didn't have any preconceived and "traditional" notions of what goes into it. Q. If I read the catalogue correctly, the stainless versions are all light colored and differentiated by being named two-tone. A fair amount of internet searching have not helped in finding people with experience in having guns refinished with Melonite. Figure 2: Cross section of 1018 steel after QPQ ® salt bath nitriding, showing the hard and wear resistant compound layer of iron nitride … I may be wrong, but I could sure use some comparative statistics on the two finishes. A friend of mine has carried both guns concealed and his Glock 26 never rusted, but his M&P 9 compact did? 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. "popup": { No rust on the slide or barrel. ." (Sounds like Tenifer.) Discussion in 'Rifle Country' started by razorback2003, Aug 23, 2015. "text": "#237afc" Frank....tool and die trade. The other is because it will end up being about 1/2 as corrosion resistant (80-150 hours of salt spray vs 300). The method features the transfer via diffusion of carbon and nitrogen from the molten salt to the surface of a steel part. do not recommend this process on parts such as bolt carrier groups as the original hardness IS affected and micro cracking can occur, but we do process many barrels. & Install'n Chemicals & Consumables Salt bath nitride entails immersing the barrel, and is finished inside and out evenly, in what we commonly call “nitride”. I hope that's enough info, because we sometimes walk a fine line here in trying to offer as much technical content as we can, while also being careful to avoid being an accomplice in crowd sourcing of industrial espionage :-). 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. NCT’s production Melonite line is capable of processing large production lots or small individual lots. What might be a viable treatment for the exposed metal? I also made sure to lap the lugs before sending it in as well. Salt-bath nitriding changes the surface area molecular framework of the metal for about four-eight microns. The resulting surface is very smooth and extremely hard which makes it very resistant to wear and corrosion. Both Companies produce a version of the same Walther Designed 99 pistol (Walther Tenifer over Steel and Smith amp;& Wesson Melonite over Stainless steel.) Joel Kendrick is a two-time IBS 600-yard Benchrest Shooter of the Year. It is a thermochemical diffusion process whereby nitrogen-bearing salts generate a controlled release of nitrogen at the interface of a ferrous part. Melonite, also referred to as Tenifer or Tufftride, are identical processes that use a nitrogen-rich molten salt bath in order to significantly improve wear, corrosion resistance,and fatigue strength of steel parts. One place on autos where salt bath nitriding is often used is on the piston of those little air springs that hold up hoods and hatchback windows. The method features the transfer via diffusion of carbon and nitrogen from the molten salt to the surface of a steel part. Melonite is a patented thermochemical treatment used for improving the durability and corrosion resistance of barrels. Thanks in advance. If you need a product/service, please check these Directories: Jobshops Capital Equip. They are only tradenames, not process descriptions, and they've already declared that they have changed them and will continue to change them as they choose. Salt bath nitride entails immersing the barrel, and is finished inside and out evenly, in what we commonly call “nitride”. 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. But more importantly, they do work for S&W, LWRC, AAC, Spike's, Beretta, KRISS. The process delivers hardened metal casings. Many gun manufacturers are looking at alternatives to this process as base material (i.e 4140) core hardness drops to an unacceptable level 36HRc. 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? Yes, this will give a "super-hard" case. 2004 but continuing through 2018. At www.durferrit.com/en/unternehmen/firmengeschichte.htm, Houghton Durferrit -- formerly part of DeGusa, but now a division of H.E.F. Joel Kendrick is a two-time IBS 600-yard Benchrest Shooter of the Year. Salt bath nitriding is a good finish but we shouldn't take it out of context, and thereby attribute almost mystical power to it. My employers plant does a lot of rifle barrels for major OEM contracts so if it were a problem we would know. A discussion started in The salt bath nitriding process features a few benefits over pre-existing chrome lining technology. All are actually nitrocarburizing processes that use molten salts as a source of nitrogen (+ some carbon). Would you nitride/melonite a rifle or cerakote one? Many gun mfgrs. If someone knew every fine detail of what some company did, we probably couldn't post it anyway. 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). Please see Melonite/Nitriding exceeds the chrome lining in almost every way and hardens the metal much deeper than chrome lining. rlanier77@hotmail.com has taken over that account. 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. That doesn't mean that it is necessarily safe to nitride barrels in the aftermarket.
