The heat treatment process
Annealing for stress reliefHeated to 530~550ºC and hold 1~2 h. Cold down
annealingIn order to eliminate hardening, which be bring out in cold-rolled, cold drawing process. Annealing needs heated to 830~880ºC in vacuum,hold 30 min.
The stabilization process
In protective media and heated to 830 ºC, hold 20min. ~ 1h, quench
Due to the stress generated by quenching, heated to 315ºC,hold 1~4h.

Precautions
Can not be hardened by heat treatment
Surface treatment can be sandblasting, polishing or pickling.
Alloy can be used 25% hydrochloric acid pickling solution at 70 ºC to clear oxidized surface
