PVD coating service also. Properties of salt bath nitriding include low material distortion, abrasion & seizure resistance & heat & corrosion resistance. Ensuring that customers get consistent, good quality products and services. Burlington Engineering provides in-house metal finishing services . 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. Standard & deep case processes available. This unique combination of salt bath treatments with intermediate surface finishing, produces a significant increase in corrosion protection while maintaining all the engineering properties initially developed through the SBN process. Salt bath nitriding is thermochemical diffusion process where nitrogen-bearing salts generate controlled release of nitrogen at interface of ferrous part. 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. The operating temperature of salt bath is 1000 ° F. – 1075 ° F., well with in the ferritic phase of ferrous materials, thus allowing the process to be performed on finished parts. Nitrocarburising is a variation of the case hardening process. In a liquid nitriding bath, which is maintained between 500 - 630°C (930 - 1165°F), nitrogen-bearing salts produce a controlled and highly uniform release of nitrogen at the surface of the workpiece. During the process both nitrogen and carbon are liberated at the surface of the ferrous component. Houston Unlimited, Inc. Top Quality Product at an Affordable Price. A salt bath uses a liquid salt solution that is usually heated between 750 degrees Fahrenheit and 1050 degrees Fahrenheit. How salt bath nitriding works. Properties of salt bath nitriding include low material distortion, abrasion & seizure resistance & heat & corrosion resistance. Salt bath nitriding is thermochemical diffusion process where nitrogen-bearing salts generate controlled release of nitrogen at interface of ferrous part. Fluidised bed/salt bath nitriding/nitrocarburising can be applied on a multitude of materials such as unalloyed steels, low alloy steels, high alloy steels, cast iron, ductile iron and sintered metals. ISO 9001:2015, AS 9100 Rev.D certified Salt bath nitriding is a metal finishing surface enhancement process that involves immersing parts in a nitrogen-bearing Melonite specific salt solution. The properties of the resulting nitrided or nitrocarburised surface are in many cases independent of the production process. Contact us for your carburizing, carbonitriding, nitriding, ferritic nitrocarburizing and vacuum processing needs. Salt bath heat treatment The wide variety of HEF Durferrit salts can be used in molten form within a temperature range of 150°C to 1300°C. Salt Bath Nitriding is performed at 560° - 570° C following necessary heat-treatment for core properties and finish machining. Liquid Nitriding Salt Bath Nitriding has been in use in a wide range of industries across the world for the improvement of surface properties like wear resistance (400-1000%) corrosion resistance, antiscuffing and anti galling properties and fatigue strength(60-100%) of … 2, Salt bath nitriding technique transfer and whole sets of furnaces; 3, Subcontract service according to customers′ request. Nitrogen diffuses into, and chemically combines with, nitride-forming elements in the metal, producing, through a catalytic reaction, a tough, ductile compound layer with exceptional mechanical properties. Place your cursor on any of our locations to reveal contact information as well as which types of services each location is capable of. By including the SBQIpolish/SBQ adjunct after SBN, surface lubricity is still greater than a chrome plated surface or a case hardened surface as determined both with and without lubrication, shown in Fig. Salt bath nitriding heat treating services. The product is then transferred to the MEL 1/TF1 tank containing the liquid Melonite salt to begin the Nitrocarburizing process. “Devis Technologies”, are ranked among the most reputed service in Nitriding Service . It is operated in a pot made from special material, and the pot is fitted with an … Parker Trutec, Inc. – Springfield Plant . Salt Bath Nitriding Xylan Coating Phosphate Conversion. Moreover the salts used also donate carbon to the work piece surface making salt bath a nitriding process. State-of-art nitrocarburizing technology, environment friendly salt bath nitriding, REACH compliance.We are a subsidiary of HEF Durrferrit in Vietnam. Salt bath nitriding —also known as ferritic nitrocarburizing (FNC)— is one of the most popular ways to achieve these results, but it isn’t the only way.
