5.Forging

H11 tool steels are forged at 900- 1120°C .Reheat is necessary when temperature below 900°C ,AISI H11 steel  should be cooled as slowly as possible in the furnace,annealing is recommended after forged.

6.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.

7.Annealing

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

8.Hardening

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

9.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.
