1、BS标准新旧钢号对照发布吋间：2008-3-2615:41:03浏览次数：84BS(BritishStandard)标准英国标准学会(BritishStandardsInstitution缩写BSI)制定的。过去的BS970标准对碳素钢、合金钢和不锈钢规定的钢号表示方法为“Enxx”(xx是1〜3位的编号数字，但不一定是顺序号，也不一定具有特定的涵义)。1967年起，英国标准协会(BSI)陆续制定、颁布了不锈钢、碳素钢和合金钢等新的数字钢号系统，并已实际应用。简单对照表如下：070M20EN3A080A15EN3B045M10EN32A080M15EN32C210M15EN32M230M07E
