1.2343 / X37CrMoV5-1 Tool Steel Forging

1.2343 / X37CrMoV5-1 Tool Steels are forged at 900- 1120°C .Reheat is necessary when temperature below 900°C , 1.2343 / X37CrMoV5-1 Tool Steels should be cooled as slowly as possible in the furnace,annealing is recommended after forged.

 1.2343 / X37CrMoV5-1 Tool Steel Stress Relieving

Stress relieving to remove machining stresses should be carried out by heat to 650°C, holding for one hour at heat, cooling in the furnace. This operation is performed to reduce distortion during heat treatment.

 1.2343 / X37CrMoV5-1 Tool Steel Annealing

Heating slowly and uniformly to 845~900℃, furnace cooling to 540℃ at a rate 10~20℃ per hour, obtain hardness HB 229 max.

 1.2343 / X37CrMoV5-1 Tool Steel Hardening

Harden from a temperature of 1000-1040℃ followed by air, oil quenching or warm bath quenching 500-550℃
C. Hardness after quenching is 50-56 HRC.

 1.2343 / X37CrMoV5-1 Tool Steel Tempering

Temper at 540°C to 650°C for Rockwell C hardness of 54 to 38.Temper minimum twice with intermediate cooling to room temperature. Holding time at temperature is minimum 2 hours.
