常用于制造無縫鋼管，模具，優(yōu)質(zhì)碳素鋼板，槽鋼，工字鋼等鋼材。

碳素鋼的分類

鋼中可分為低碳鋼、中碳鋼和高碳鋼。

低碳鋼--含碳量一般小于0.25%；

中碳鋼--含碳量一般在0.25～0.60%之間；

高碳鋼--含碳量一般大于0.60%。

鋼中除含有碳(C)元素和為脫氧而含有一定量硅(Si)(一般不超過0.40%),錳(Mn)(一般不超過0.80%,較高可到1.20%)合金元素外,不含其他合金元素(殘余元素除外)。

鋼中含碳量低于2.1%為鋼，含碳量高于2.1%為鐵。

鋼中含碳量越高其韌性越差，鋼中含鐵量越高其韌性越好。

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.
