英语翻译
Steel is an alloy of iron and carbon with other elements added to produce specific properties.the various types of steel can be grouped under two major headings.
carbon steel .a steel in which the main alloying element is carbon .carbon steels are further divided into three groups .
low carbon steel .this steel has a carbon content of less than 0.30 percent .it is the most common type and is often called mild steel .it is relatively inexpensive .ductile,soft ,and is easily machined and forged.mild steel cannot be heat-treated .low carbon steel is a general purpose steel.
Medium carbon steel.this steel has a carbon content between 0.3 percent and 0.8percent .harder and stronger than mild steel ,it can be hardened by heat treating.medium carbon steel is most commonly used for forgings,castings ,and macheined parts for automobiles ,agricultural equipment ,machines ,and aircraft .
High carbon steel .this type of steel is easlily heat-treated to produce a strong ,tough part .the material has a carbon content above 0.8 percent .it finds wide use in hand tools ,cutting tools ,springs,and piano wire.
high alloy steel.these steels contain significant amounts of other elements in addition to carbon.the common high allloy steels are:
stainless steel which is produced by using chromium as a significant alloying element along with nickel and other metals.the result is a tough,hard ,corrosion-resistant metal.
Tool steel which is a special group of high carbon steels produced in small quantities to high quality specifications.tool steels are used for a wide range of cutting tools and forming dies.
Manganese steel which is an alloy containing 12 percent manganese and one percent carbon.This metal is used in mining ,railroad ,and construction equipment because of its high tensile strength.

钢是铁和其他元素碳合金添加到具体的详细性能,生产各类钢可根据两大类分组.
碳钢.一钢中的主要合金元素是碳.碳钢进一步分为三组.
低碳钢.这个钢只有不到百分之0.30的碳含量.这是最常见的类型,通常被称为低碳钢.也相对便宜.韧性,柔软,易于加工和forged.mild钢不能热治疗.低碳钢是一种通用钢材.
中碳steel.this钢有0.3至百分之0.8percent碳含量.更难,比软钢强,它可以通过热treating.medium碳钢淬火是最常用的锻件,铸件用于汽车macheined及零部件,农业设备,机器和飞机.
高碳钢.这种类型的easlily钢热处理后产生强烈的,艰难的部分.材料有百分之0.8以上的碳含量.找到在广泛使用手工工具,刀具,弹簧,钢琴线.
高合金steel.these钢除含有大量的其他因素共同的carbon.the高allloy钢材：
不锈钢是由作为一个重要合金与其他metals.the镍和铬元素产生的结果是一个艰难,艰苦,耐腐蚀金属.
工具钢是一种高碳钢小批量制作高质量specifications.tool钢集团特殊钢用于切割工具的广泛成型模具.
锰钢这是合金中的锰和百分之十二碳百分之一.这种金属是用于矿山,铁路和建筑设备由于其具有高抗张强度.
