Heat treatment Related

  • Annealing of 20CrMnTi Alloy Gearing 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 20CrMnTi Gearing steel will get Hardness MAX 248 HB (Brinell hardness).

  • Quenching and temperature of 20CrMnTi gear steel

Heated slowly to 788°C, Then put in salt-bath furnace keep 1191 ℃to 1204 ℃.quenching by oil get 60 to 66 HRc hardness. High temperature tempering: 650-700℃,cool in air, get hardness 22 to 30HRC. Low temperature tempering: 150-200 ℃, Cool in ari, get 61-66HRC hardness.

  • Hot work and cold work of 20CrMnTi Alloy Gearing steel

GB 20CrMnTi steel can hot worked at 205 to 538°C, 20CrMnTi Bearing/Gearing steel can be cold worked using conventional techniques in the annealed or normalized conditions.


Mechanical Properties

The mechanical properties of annealed GB 20CrMnTi Gearing steel (typical for steel) are outlined in the table below:

  Tensile Yield Bulk modulus Shear modulus Poisson’s ratio Thermal conductivity
