CBS-50 NiL

UNS #K91231

CBS-50 NiL VIM VAR is a carburizing bearing and gear steel designed for service up to 600F (316C). The chemistry is engineered such that when suitably carburized and heat treated the case wil have a microstructure of fine tempered martensite with an even distribution of fine carbides. The primary advantage of CBS-50 NiL VIM VAR steel over conventional through hardening M50 is the relatively high fracture toughness properties of the core.
