Heat treatment Related

  • Annealing of 16MnCr5|1.7131 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 16MnCr5|1.7131 gearing steel will get Hardness MAX 248 HB (Brinell hardness).

  • Quenching and temperature of 16MnCr5 Alloy gearing 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 16MnCr5 gearing steel

DIN 16MnCr5?gear steel can hot worked at 205 to 538°C, 16MnCr5|1.7131 gearing steel can be cold worked using conventional techniques in the annealed or normalized conditions.
