What Is The Heat Treatment Process Of High Chromium Cast Iron?
Jul 01, 2023| Commonly used heat treatment processes are:
1. Stress relief annealing, the purpose is to eliminate casting stress and reduce the tendency of deformation and cracking.
2. Surface quenching, specifically flame surface quenching, contact electric heating surface quenching, induction heating surface quenching, the purpose is to improve the hardness and wear resistance of the casting surface. If it is high chromium ductile iron, it can also be normalized and austempered.
