Technical Parameter of Carbon Steel Rod

Carbon steel bar is a kind of solid long steel, and the common ones are round steel, square steel, hexagonal steel, octagonal steel, etc. Round steel is often used to make steel bars, bolts and various mechanical parts, as well as billets for seamless steel pipes. Square steel refers to steel that is rolled or processed into a square section, which can be divided into hot-rolled and cold-rolled.

Classification of Carbon Steel Rod

Round bars are divided into three types:

Hot rolled round bars, forged round bars and cold drawn round bars according to the process section.

According to the chemical composition (ie carbon content)

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

According to the quality of steel

It can be divided into ordinary carbon steel round steel and high-quality carbon steel round steel.

According to the use

It can be divided into carbon structural steel and carbon tool steel.

  • 08-25 steel has low carbon content, low strength and hardness, good plasticity, toughness and weldability. It is mainly used to manufacture stamping parts, welded structural parts and mechanical parts with low strength requirements.
  • 30-55 belongs to quenched and tempered steel, which has good comprehensive mechanical properties after being quenched and tempered, and is mainly used to manufacture mechanical parts with greater stress.
  • The steel above 60 belongs to spring steel, which can obtain a higher elastic limit after heat treatment, and is mainly used for the manufacture of elastic parts.
