P20模具钢是一种模具焊材的型号，最早的是P20，紧接着P20H，P20Ni相继问世。 P20钢材适用于制作塑料模和压铸低熔点金属的模具材料。此钢具有良好的可切削性及镜面研磨性能。 中国牌号:  3Cr2Mo标    准: GS-2311 化学成份:碳 C ：0.38锰 Mn：1.30铬 Cr： 1.85钼 Mo ：0.40硫 S ：0.008使用方法:P20模具钢已预先硬化处理至285-330HB（30-36HRC），与瑞典618德国GS-2311状态相当，可直接用于制模加工，并具有尺寸稳定性好的特点，预硬钢材才可满足一般用途需求，模具寿命可达50W模次。 特性:硬度均匀，具有良好的抛光性能及光蚀刻花性能，加工性能佳 真空脱气精炼处理钢质纯净，适合要求抛光或蚀纹加工塑胶模。 预硬状态供货，无需再热处理可直接用于模具加工，缩短工期。 经锻轧制加工，组织致密，100%超声波检验，无气孔，针眼缺陷。 用途:适用于电视机前壳、电话机、饮水机、吸尘器等塑料模及模架。热塑性塑胶注塑模具，挤压模具。热塑性塑料吹塑模具。重载模具主要部件。冷结构制件。常用于制造电视机壳，洗衣机，冰箱内壳，水桶等。 加硬处理:为提高模具寿命达到80万模次以上，可对预硬钢实施淬火加低温回火的加硬方式来实现。淬火时先在500-600℃预热2-4小时，然后在850-880℃保温一定时间（至少2小时），放入油中冷却至50-100℃出油空冷，淬火后硬度可达50-52HRC，为防止开裂应立即进行200℃低温回火处理，回火后，硬度可保持48HRC以上 氮化处理:氮化处理可得到高硬度表层组织，氮化后的表层硬度达到650-700HV （57-60HRC）模具寿命可达到100万次以上，氮化层具有组织致密，光滑特点，模具的脱模性及抗湿空气及碱液腐蚀性能提高。
