鋼的編號和表示方法和中外鋼號對比不銹鋼性能對比

1、    鋼的編號和表示方法 用國際化學(xué)元素符號和本國的符號來表示化學(xué)成份，用阿拉伯字母來表示成份含量：如：中國、俄國 12CrNi3A 用固定位數(shù)數(shù)字來表示鋼類系列或數(shù)字；如：美國、日本、300系、400系、200系； 用拉丁字母和順序組成序號，只表示用途。 我國的編號規(guī)則 采用元素符號 用途、漢語拼音，平爐鋼：P、 沸騰鋼：F、 鎮(zhèn)靜鋼：B、甲類鋼：A、T8：特8、GCr15：滾珠 合結(jié)鋼、彈簧鋼，如：20CrMnTi 60SiMn、（用萬分之幾表示C含量） 不銹鋼、合金工具鋼（用千分之幾表示C含量），如：1Cr18Ni9 千分之一（即0.1%C）,不銹 C0.

2、08% 如0Cr18Ni9,超低碳C0.03% 如0Cr17Ni13Mo 國際不銹鋼標(biāo)示方法 美國鋼鐵學(xué)會是用三位數(shù)字來標(biāo)示各種標(biāo)準(zhǔn)級的可鍛不銹鋼的。其中： 奧氏體型不銹鋼用200和300系列的數(shù)字標(biāo)示， 鐵素體和馬氏體型不銹鋼用400系列的數(shù)字表示。例如，某些較普通的奧氏體不銹鋼是以201、 304、 316以及310為標(biāo)記， 鐵素體不銹鋼是以430和446為標(biāo)記，馬氏體不銹鋼 是以410、420以及440C為標(biāo)記，雙相（奧氏體鐵素體）， 不銹鋼、沉淀硬化不銹鋼以及含鐵量低于50%的高合金通常是采用專利名稱或商標(biāo)命名。 世界各國不銹鋼標(biāo)準(zhǔn)鋼號對照表中國GB1220-9284GB3220-92
