Heat Treatment Process Requirement:

The below technical details strictly follow DIN 1.3207 standard to get right ratio among different crystal organization,to let this material performance can be as good as required.Below is the details:

Soft Annealing:

Heat to 800-860C,cool slowly in furnace.This will produce a maximum Brinell hardness of 300.

Stress Relieving:

Stress relieving to remove machining stresses should be carried out by heating to 600-650″C,holding for one hour at heat,followed by air cooling.This operation is performed to reduce distortion during heat treatment.

Hardening:

Harden from a temperature of 1200-1230″C followed by oil,air quenching or warm bath at 540″C.Hardness after quenching is 64-66 HRC.

Tempering:

Tempering temperature:540-570″C,at least 2x for 65-67 HRC.Hardness after tempering is 64-67 HRC.
