Heat treatment related

  • Annealing the 20CrMnTi alloy bearing / gear steel

Heated slowly to ℃ 790-810 and allow enough times, let the steel be heated thoroughly, then slowly cool in the oven. Different ways of annealing get different hardness. The 20CrMnTi bearing / the gear steel have a hardness of max. 248 HB (Brinell hardness).

  • Quenching and temperature of 20CrMnTi alloy bearing / gear steel

Slowly heated to 788 ° C, then inserted in salt bath oven hold ℃ to 1191 1204 ℃ .quenching through oil, 60 66 HRc to get to hardness. Mitigating the high temperature: 650-700 ℃, cool in air, hardness 22 get at 30HRC. Mitigate the low temperature: 150-200 cool ℃, in ari, get hardness 61-66HRC.

  • Hot work and cold working of 20CrMnTi alloy bearing / gear steel

Steel canhot GBs 20CrMnTi machined at 205 to 538 ° C, 20CrMnTi bearing / gearbox steel can is cold worked using conventional techniques in annealed or normalized conditions.
