摘要
本文通过对4cCrNiMo钢表面微渗碳淬火加底温回火处理新工艺的研究,认为对提高颗粒模寿命,取代进口.有着实际应用价值。
In this paper;by the study of surface micro-carburizing,hardening and low-temperature tempering process of 40CrNiMo steel.it is considered that this process helps to increase the survice life of pellet dies,replace imports thus it possesses great worth in application.
