          详细介绍:

          常用于制造无缝钢管,模具,优质碳素钢板,槽钢,工字钢等钢材。


          碳素钢的分类


          钢中可分为低碳钢、中碳钢和高碳钢。

          低碳钢--含碳量一般小于0.25%;

          中碳钢--含碳量一般在0.25~0.60%之间;

          高碳钢--含碳量一般大于0.60%。

          钢中除含有碳(C)元素和为脱氧而含有一定量硅(Si)(一般不超过0.40%),锰(Mn)(一般不超过0.80%,较高可到1.20%)合金元素外,不含其他合金元素(残余元素除外)。

          钢中含碳量低于2.1%为钢,含碳量高于2.1%为铁。

          钢中含碳量越高其韧性越差,钢中含铁量越高其韧性越好。

          ommonly used in the manufacture of seamless steel tubes, molds, high-quality carbon steel, channel steel, I-beam and other steel.


          Classification of carbon steel


          Steel can be divided into low carbon steel, medium carbon steel and high carbon steel.


          Low carbon steel - the carbon content is generally less than 0.25%;


          Medium carbon steel - the carbon content is generally between 0.25 and 0.60%;


          High carbon steel - carbon content is generally greater than 0.60%.


          In addition to carbon (C) elements and containing a certain amount of silicon (Si) (generally not more than 0.40%), manganese (Mn) (generally not more than 0.80%, up to 1.20% higher) alloying elements, Contains no other alloying elements (except for residual elements).


          The carbon content of the steel is less than 2.1% for steel, and the carbon content is higher than 2.1% for iron.


          The higher the carbon content of the steel, the worse the toughness. The higher the iron content in the steel, the better the toughness.
