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. can be accommodated. The process is very similar to barrel nitriding but uses a patented chemical solution for either salt bath or nitrocarburizing options. It is widely used to enhance the performance of titanium, chromium, and aluminum alloyed steels, as … The salt bath process uses the principle of the decomposition of cyanide to cyanate and the liberation of nitrogen within the salt for diffusion into the steel surface. The salt bath nitriding process features a few benefits over pre-existing chrome lining technology. We manufacture Nitriding, Nitro-carburizing Salts and Fluids used in Salt Bath Nitriding and Gas Nitriding. During the nitriding process, a combination of nitrogen and carbon is diffused into a metal surface using a high-temperature salt bath. salt bath nitriding equipment Since the introduction of salt bath nitriding (or ferritic nitrocarburizing) to North America in the 1950s, Kolene has been providing the necessary process equipment. Salt Bath Nitriding (DHSN) ... the surface due to differences in chemical potential that then allows nitrogen and carbon species to diffuse from the salt into the steel substrate. Salt bath nitriding. Salt spray test results per ASTM B 117 and DIN 50021 show improved benefits from the fluidised bed/salt bath nitriding/nitrocarburising process over competing processes. (a) salt bath (liquid) nitriding, where the source of nitrogen (and also carbon) is molten salt. It is a thermochemical diffusion process whereby nitrogen-bearing salts generate a controlled release of nitrogen at the interface of a ferrous part. Liquid nitriding is used where low case-depth is required and is then cheaper. Besides, the process has few advantages, quick heating of the work piece being the only one worth mentioning. The client can avail from us the high grade salt bath Nitriding services. Salt-bath nitriding [3] can be an economical method providing that both the salt-bath chemistry and cleanliness are maintained (Fig. Salt baths presents dangers to the environment and to the personal safety of the operators. The following table lists the typical properties produced by CST’s standard Ni-Surf process. The process may also be used as a part of liquid Nitriding treatment. Salt bath nitriding is a thermochemical process in which nitrogen and carbon are diffused simultaneously into the surface of the material. The heat requirements for liquid are lower than for the gas technique, and the hardened compound on the surface of the component is thicker. In salt bath nitriding the nitrogen donating medium is a nitrogen-containing salt such as cyanide salt. Salt Bath Nitriding. The process delivers hardened metal casings. Modern practitioners have perfected nitriding into several sub-processes: gas nitriding (the most widely used), salt bath nitriding, and plasma nitriding. Aerated bath nitriding is a process in which measured amounts of air are pumped through the molten bath. Liquid nitriding or salt bath nitriding was developed as an economic means of providing shallow cases for wear resistance. Figure 2: Cross section of 1018 steel after QPQ ® salt bath nitriding, showing the hard and wear resistant compound layer of … Preferably, air flows through the bath. Salt bath nitriding can be an economical method of nitriding providing that both the salt bath chemistry and the salt bath cleanliness are maintained. The salts used also donate carbon to the workpiece surface making salt bath a nitrocarburizing process. Salt Bath Nitriding. Salt-Bath Nitriding. Salt bath nitriding. Unlike nitriding methods using a salt bath, gas nitriding is a more flexible process with easier disposal of the nitriding agent. Application & materials. Salt bath nitriding / liquid nitriding is a subcritical surface enhancement process holding the longest track record of success over any case hardening technology. ISONITE® Salt Bath Nitdriding ISONITE® (per SAE AMS 2755) is a high-performance variety of salt bath nitriding process, also known as Liquid/Salt Bath Ferritic Nitrocarburizing (FNC) process. Mission Statement. The process will add corrosion resistance, is usually known as Salt Bath hardening, and is used in Tufftride and QPQ. in diameter or 107 in. In salt bath nitriding the nitrogen donating medium is a nitrogen containing salt such as cyanide salt. Special cycles are employed for deeper case requirements. Numerous improvements and design enhancements have occurred over the years. The process is carried out at 750-1050°F, making it faster than gas nitriding. It is carried out at temperatures between 400 o C and 570 o C for a short period, up to a few hours. It is mandatory that the salt-bath chemistry is checked at the commencement of each shift and that the appropriate additions of salt are made to return the bath to its operational strength. ... To treat a surface, manufacturers use aluminizing, carburizing, cyaniding, and nitriding salts. The operation is simple and the processing time is faster than the … Friction Technologies Incorporated in the year 1997, it has been providing a wide range of reliable nitriding services that consists of salt bath nitriding & oxiding process, nitro carburizing process, surface treatment process, better corrosion resistance coatings, and many more. To learn more about salt-bath nitriding for barrels, or to place a processing order with MMI-TruTec, email joelkndrck [at] aol.com, or call Joel at (704) 616-6442. We offer: Nu-Tride ® Salt Bath Nitriding (equivalent to Melonite ® process) Nu-Tride ® Salt Bath Nitriding Q.P. Normally the cyanide salt is melted and aged at the nitriding temperature for 12-24 hours, before the parts are immersed into the bath. Parts up to 57 in. Joel, a past 600-yard Shooter of the Year, is very knowledgeable about both shooting and the nitriding process.
