According to the carbon content, round steel can be divided into low carbon steel, medium carbon steel and high carbon steel. Low carbon steel with less than 0.25% C is widely used for deep drawing parts such as automobiles and cans due to its good deep drawing and weldability. 20G is the main material for ordinary boilers. In addition, low carbon steel is also widely used as carburizing steel in machinery manufacturing industry. 0.25-0.60% C is medium carbon steel, which is mostly used in quenching and tempering state to make parts for machinery manufacturing industry. More than 0.6% C is high carbon steel, which is mostly used for manufacturing springs, gears, rolls, etc. Round steel (grade I steel) belongs to ordinary low carbon steel, and other steel bars are mostly alloy steel; The strength of round steel is lower than that of other steel bars. That is to say, compared with other steel bars, round steel bars with the same diameter can bear less tensile force, but the plasticity of round steel bars is stronger than that of other steel bars. That is to say, round steel bars have larger deformation before being pulled off, while other steel bars have much smaller deformation before being pulled off. | Standerd | JIS / ASTM / GB / DIN / EN /AISI |
