In our country steels are classified mainly in three ways according to the state standards; by chemical composition, by refining methods, and by the uses.
在我国，根据国家标准主要用3种方法对钢进行分类，即按化学成分，按冶炼方法及按用途来分。
2.
I think the second way to classify steels is simple. By refining methods steels can be divided into three classes: open-hearth furnace steel, converter steel, and electric furnace steel.
我想第二种分类方法较简单。按冶炼方法，钢可分为平炉钢、转炉钢和电炉钢。

but the percentages of carbon and other elements and the methods by which iron and steel is produced, as well as the processes to which they may be subjected, so change the characteristic properties
但由于炭和其他元素的含量不同，钢铁冶炼方法不同以及加工过程不同，从而改变了它们的特性
