摘　　要：冷作模具钢工作时承受压缩、拉伸、弯曲、冲击、摩擦等很大的变形抗力,它的性能和热处理工艺对模具寿命有着决定性的影响。其使用性能主要包括耐磨性、韧性、强度、抗疲劳性能和抗咬合性,热处理工艺性能主要包括:淬透性,淬硬性,耐回火性,过热敏感性,氧化脱碳倾向,淬火变形和开裂倾向等。冷作模具钢的力学性能、工艺性能和承载能力进行分组,使其具有更合理的适用范围来选用冷作模具钢,从而能够有效的提高冷作模具使用寿命。Cold-working die steel under compression, tensile, bending, impact, friction and mechanical force in the using. Its performance and heat treatment process has a decisive influence on the service life of die. Its performance mainly includes the wear resistance, toughness, strength, fatigue resistance and seizure resistance, heat treatment pegrormance mainly includes： hardenability, hardening, tempering resistance, overheating sensitivity, oxidation and decarburization tendency, quenching deformation and cracking tendency. Grouping according to mechanical behavior ,process performance and bearing capacity of Cold-working die steel mechanical. Which has applied more reasonable and rational selection of Cold-working die steel, it can effective improve the service life of die.
