CBS-50 NiL™

CBS-50 NiL™ is a carburizing bearing and gear steel designed for service temperatures up to 600°F (316°C). The chemistry is engineered such that when suitably carburized and heat treated, the case will have a microstructure of fine tempered martensite with an even distribution of fine carbides. The primary advantage of CBS-50 NiL™ steel over conventional through hardening M50 is the relatively high fracture toughness properties of the core. Because the alloy can be carburized, surface stresses can be controlled to provide excellent rolling contact fatigue characteristics.

This carburizing steel is used in critical aircraft engine bearings. It is double vacuum melted (VIM-VAR) for optimum cleanliness and performance characteristics. Vacuum arc remelting is employed to produce a preferred ingot structure for superior mechanical properties.
