模具的質(zhì)量直接影響著壓力加工工藝的質(zhì)量、產(chǎn)品的精度產(chǎn)量和生產(chǎn)成本。模具的好壞，對(duì)產(chǎn)品質(zhì)量的影響是很明顯的。而模具鋼的質(zhì)量又是直接影響了模具的質(zhì)量。為何客戶要的產(chǎn)品總是做不好？你試想過是模具鋼的問題嗎？
給模具選材，除了要考慮到滿足工作條件和工藝性能要求，也要必須考慮經(jīng)濟(jì)性原則，盡可能地降低制造成本。一般來說，塑膠模具鋼必備之性能主要包括強(qiáng)度和韌性、硬度、耐磨性、耐蝕性（有些塑料如PVC、POM和PP等，具有腐蝕性，會(huì)使模具型腔腐蝕生銹。耐腐蝕性的鋼材有S136H和PAK90等）。同種模具鋼材，不同國(guó)家之間牌號(hào)是不同的。世界主要模具鋼材國(guó)家日本、德國(guó)、瑞典等各自有自己的牌號(hào)，下面這個(gè)表格，我們擷取了常見模具鋼材世界幾個(gè)主要國(guó)家的牌號(hào)對(duì)比，希望對(duì)大家有參考作用。
