1.2067 is a construction steel of spheroidal bearing steel grades which exhibits high hardness, abrasion resistance and relatively easy mechanical treatment. 102Cr6 is used for the production of bearings and other pressure and friction-resistant components that do not operate at elevated temperatures, and the dimensions used are limited to approximately 30mm of thickness.
FOllowing is production standard of 1.2067 forged material
EN 10132-4: 2000 Cold rolled narrow steel strip for heat treatment. Technical delivery conditions. Spring steels and other applications

102Cr6 forged material Heat treatment way is as following
Annealing of 102Cr6 Alloy bearing steel
Soft Annealing
Heat to 720-7509c, cool slowlyin furnace to <5509c, then air. This will produce a maximum iBrinell hardness of 225.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 650Pc,holding for 1-2 hours at heat, follwed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Harden from a temperature of 790-8209c, 820-8609c followed by water or oil quenching.Hardness after quenching is 63-67, 63-66 HRC.
Tempering
Tempering temperature: 150-3009c. Hardness after tempering is 56-65 HRC.
