Heat treatment Related
- Annealing of 100Cr6 Alloy bearing steel
Slowly heated to 790-810 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. Different annealing ways will get different hardness.The 100Cr6 bearing steel will get Hardness MAX 248 HB （Brinell hardness）.
- Quenching and temperature of 100Cr6 Alloy bearing steel
Heated slowly to 860°C, Then quenching by oil get 62 to 66 HRc hardness. High temperature tempering: 650-700℃，cool in air, get hardness 22 to 30HRC. Low temperature tempering: 150-170 ℃， Cool in ari, get 61-66HRC hardness.
- Hot work and cold work of 100Cr6 Alloy bearing steel
Din 100Cr6 steel can hot worked at 205 to 538°C, 100Cr6 Bearing steel can be cold worked using conventional techniques in the annealed or normalized conditions.
