M50-NiL High Performance Carburizing Bearing and Gear Steel
Categories:	Metal; Ferrous Metal; Alloy Steel; Carbon Steel; High Carbon Steel
Material Notes:	A carburizing bearing and gear steel designed for service temperatures up to 600°F. 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. Improved 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. Information provided by Latrobe and the reference(s).
