‘mild steel’ 真正的特点是什么?
我的AQA Science mild steel is one type of low carbon steel and low carbon steel is soft and wasily shaped,so it is very easily pressed into shaped.
但是牛津词典说:mild steel is a type of steel containing very little carbon which is very strong but no wasy to shape.
新手上路,还请多关照
各位不好意思
小人打错字了
wasily 其实是 easily
and wasy 其实是easy
以后一定double check..

mild steel 直接翻译的话就是“软钢”,词典里解释的也很清楚,是低碳钢(不是高碳钢也不是合金钢),容易变形的钢.实际上我们实际接触的冷轧和镀锌钢材大多都是 mild steel,一般来说就是钢材中碳含量低于0.10%或者在0.10%左右的碳素钢,比如SPCC、DC01、ST12这类.钢铁中出了铁元素之外,还有C、Si、Mn、S、P等元素,其中碳(C)含量对材质软硬程度影响比较大,一般说来含碳量低强度低,延伸率高,硬度也相对低一些,所以变形能力就比较好.
