1.2738 Steel Sheet Heat Treatment
Softening Annealing
The temperature of annealing is 710-740℃. The time of heat preservation
depends on what is the size of it. The stand is that per 25mm of the diameter
then the time must be 1 hour. Then furnace cooling after heat preservation.

Stress Relieving
The temperature is 600°C at the condition of annealing. And on the condition
of quenching and tempering, the temperature must be 550°C. The time of heat
preservation is according to the stand as the same. Then furnace cooling after
heat preservation.

Quenching and Tempering
The temperature for preheat needs to be 500~600°C. The temperature of
quenching is 840~880°C and keep it for about 30 minutes. By the way, the mold
base must at the production for atmosphere to get quenching to avoid the
oxidation and decarbonization happen. Then need to oil cooling. When 1.2738
steel is cooled to 50°C~70°C, take it tempering immediately.

And the requirement for the time of heat preservation is the same, at least 2
hours. The temperature of tempering is
180°C/200°C/300°C/400°C/500°C/600°C; and the hardness is 52HRC/51HRC/48
HRC/46HRC/42HRC/34HRC.

Hardening
It can be hardening to raise the surface hardness to 50HRC. Oil cooling after
the hardening.
