  • Gli acciai vengono classificati, secondo la normativa europea (EN), in due sistemi equivalenti di designazione: * quello alfanumerico: es. S235JR; * quello numerico: es 1.0037. Il primo dei due sistemi è descritto dalla UNI EN 10027-1 mentre il secondo dalla UNI EN 10027-2. (it)

  • 鋼質等級是由 标准组织 制定的,用于对各种钢铁产品进行分类标识的方法。 分級的標準首先是化學成分中減少不必要的雜質,分成普通鋼和優質鋼,合格的普通鋼中磷和硫含量少於約萬分之五級,更少便是優質鋼,優質鋼又細分優質鋼和高級優質鋼,後者還可以再細分。 然後是對各種材料性能的測驗,各地和國際都制定一些標準方優用家。 例如: * 国际标准化组织 ISO/TS 4949:2003 * 欧洲标准化委员会 EN 10027 * 中华人民共和国国家标准 GB/T 221 在中国,钢质等级也称为钢铁牌号,简称钢号。 (zh)
