6:Heat Treatment
Normalizing For 15CrNi6
Nominal normalizing temperature:850-880°C
Hold the temperature for several hours
Cooling in the air
Annealing For 15CrNi6
Nominal Annealing temperature:650-700°C
Cool slowly in the furance
Maximum Brinell hardness of 229
Hardening and Tempering(QT) For 15CrNi6
Nominal Hardening temperature:820-870°C
Hold at this temperature then quench in oil or water
Tempering as soon as possible when the temperature low to ambient
Heat uniformly to the suitable temperature.
keep the material out of the furnace ,then cool in the air
