Heat Treatment for Mold Steel — Complete Guide：核心技术要点、操作步...

[yao86]

Common heat treatment processes for mold steels:

1. Annealing — stress relief, soften for machining
2. Quenching — harden to HRC 55-65
3. Tempering — reduce brittleness, adjust final hardness
4. Nitriding — surface hardening for wear resistance (0.1-0.3mm case)
