Of course I know. according to the amount of the carbon content, carbon steels can be divided into low-carbon steel, medium-carbon steel and high--carbon steel.
根据碳元素的含量，碳素钢可再分为低碳钢、中碳钢和高碳钢。

We smell more than sixty kinds of steel here, such as low alloy steel, carbon structural steel and shipbuilding carbon steel.
这儿冶炼六十多种钢，如低合金钢、碳素结构钢和船用碳素钢等。

There are four broad classifications of steel: carbon steels, alloy steels, high-strength low-alloy steels and stainless steels.
钢材大致辞可分为四类，即：碳素钢、金钢、强度低合金钢和不锈钢。
