CARPENTER VIM-VAR 52100 is a high-carbon steel containing nominally 1.40% chromium. It is produced by vacuum-induction melting (VIM), followed by vacuum-arc remelting (VAR) to meet the exacting demands of bearing manufacturers for a clean steel of uniform microstructure. It is deep hardening and has high resistance to wear. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, and machining. Filing Code: SA-412. Producer or source: Carpenter.
