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.
