摘要
Cr12MoV钢是常用的冷作模具钢,通过合理的热处理可显著提高其表面硬度、耐磨性和使用寿命,包括锻造后的退火、低温和高温淬火、回火及精加工后的表面硬化处理。介绍了这些工艺的应用实例。
Cr12MoV steel is a commonly used cold-work die steel,and reasonable heat treatments,such as annealing after forging,quenching from lower or higher temperature,tempering,and surface hardening after fine machining,can render its surface hardness,wear resistance and service life much better.Some examples of the foregoing heat treating processes were introduced.
