怎么分别模具钢的种类（如何选好模具钢）
模具的质量直接影响着压力加工工艺的质量、产品的精度产量和生产成本。模具的好坏，对产品质量的影响是很明显的。而模具钢的质量又是直接影响了模具的质量。为何客户要的产品总是做不好？你试想过是模具钢的问题吗？
给模具选材，除了要考虑到满足工作条件和工艺性能要求，也要必须考虑经济性原则，尽可能地降低制造成本。一般来说，塑胶模具钢必备之性能主要包括强度和韧性、硬度、耐磨性、耐蚀性（有些塑料如PVC、POM和PP等，具有腐蚀性，会使模具型腔腐蚀生锈。耐腐蚀性的钢材有S136H和PAK90等）。同种模具钢材，不同国家之间牌号是不同的。世界主要模具钢材国家日本、德国、瑞典等各自有自己的牌号，下面这个表格，我们撷取了常见模具钢材世界几个主要国家的牌号对比，希望对大家有参考作用。加微信18824631817申请艾邦模具交流群。
