100Cr6 bearing steel good overall performance, quenching and tempering, high hardness and uniform, good wear resistance, high contact fatigue strength. Good hot workability of steel, ball machined after a good machinability. 100Cr6 is a through hardening bearing steels intended for rolling contact and other high fatigue applications. In the hardened condition the high hardness, high strength and high cleanliness provides the steel with the right properties to withstand high cycle, high stress fatigue. 100Cr6 is mainly used for small and medium sized bearing components. It is also regularly used for other machine components that require high tensile strength and high hardness. The hardenability approximately corresponds to a ring with max. 17 mm wall thickness.
