what is aisi 440
ASTM A276 standard grade 440C stainless steel is a high carbon martensitic stainless steel. Otai steel supplies reliable quality of 440c steel materials.
W. Sn. AISI 440C is a high-carbon chromium steel designed to provide stainless properties with maximum hardness. It has been used primarily as a bearing steel, and is used in the hardened plus tempered condition. When heat-treated, Type 440C attains the highest hardness of any stainless steel (about Rockwell C 60). AISI 440 stainless steel from stock - Stahlhandel GröditzThe materials AISI 440 can be described as Martensitic stainless steels. They vary by the alloy composition, especially the percentage of carbon. The other alloying elements are similar. The steel grade 1.4112 is also known as AISI 440 B. Due to the high carbon content this stainless steel has a high hardenability and is corrosion resistant.
AISI 440 steel is used to manufacture bearing parts working in corrosive environment, and can also be used to manufacture high quality tools (medical scalpels, scissors and blades, surgical and dental instruments), molds and dies, springs, cutlery, valves and valve components, cams, gears, shafts, ball bearings, nozzles and measuring tools.
