Steels for bearings

Lean Steels: Microstructure. Steels with carbon concentrations in the range 0.8-1.1 wt% and the total substitutional solute content less than 3 wt%, designed originally for machining tools, have historically dominated the mass market for bearings [ s10, 9].They can be made martensitic by quenching in oil or salt, from a temperature where the material is mostly austenite.
