Unifit Metalloys Inc. is one of the known traders of Stainless Steel ASTM A194 Grade 8MLCuN Fasteners, which is available in different sizes and shapes for our customers. Stainless Steel ASTM A194 Grade 8MLCuN Nuts offers in connection with austenitic weld metal and too high heat input the addiction to heat cracks exists. In comparison to carbon steel, Stainless Steel ASTM A194 Grade 8MLCuN Bolts are tougher and tend to work harden quickly, because by using all of the common welding processes it can be easily welded. Exposure to temperatures above about 400 Degree C will result in progressive removal of work hardening effects in Stainless Steel ASTM A194 Grade 8MLCuN Washers; at approximately 800 Degree C the strength will be similar to an annealed alloy.
While Stainless Steel ASTM A194 Grade 8MLCuN Screws can be easily welded and is relatively ductile, cold work practices should be carried out with caution. Do not forge Stainless Steel ASTM A194 Grade 8MLCuN Hex Head Nuts below 1800 Degree F (982 Degree C), because rapid cooling is required to maximize corrosion resistance.
Stainless Steel ASTM A194 Grade 8MLCuN Hex Head Bolts is also used in furnace parts, heating elements, heat exchangers, kiln liners, boiler baffles, auto exhaust parts; refinery, chemical and food processing equipment. Stainless Steel ASTM A194 Grade 8MLCuN Hex Head Screws is used in combustion tubes, refractory anchor bolts, fire box sheets, furnace components and other high temperature containers.
