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.
