※ 引述《wainlu (pour moiNN )》之銘言:
: 那我想問一下
: CHARRIOL的飾品到底是什麼材質阿?
: 曾經有一個專櫃小姐跟我說"純剛"
: 後來被我學化學的同學說沒有純剛這種東西....
: 我是完全不懂啦.....
: 大家可以解答一下嗎....?
Steel一般指的是鋼...
碳含量在2.1%以下...
以上則稱為鑄鐵(Cast Iron)
鋼通常是Fe跟C的合金
且C不是一般所見的石墨態
而會與Fe形成Fe3C的carbide
至於鑄鐵(Cast Iron)通常不只含Fe跟C
通常最常見的還有Si
故可視為是Fe C Si的三元合金(tertiary alloy)
所以店員指的純鋼可能是指不含Si或是含雜質量極少的鋼
至於不鏽鋼(Stainless Steel)則是合金鋼的一種
含有12%以上的Cr,如此才可有防鏽的效果
一般常見的有304SS, 316SS, 347SS
除了加入Cr防鏽亦會添加其他元素,如Mo來防止氯離子腐蝕的316SS
當然不鏽鋼的成分不只有上面提到的這些元素,
還包含了Ni, Mn, Si等數種元素,
各種不鏽鋼成份的規範也都記載在ASTM規範裡!~
以上.......
