10mm deformed building concrete iron rod carbon steel

Short Description:

Round steel is a long, solid steel bar with a circular cross-section. Its specifications are expressed in diameter, unit mm (mm), such as “50mm” means the diameter of 50mm round steel.

Round steel is classified as hot rolled, forged and cold drawn. Hot rolled round steel is 5.5-250 mm in size. Among them: 5.5-25 mm small round steel mostly to straight strips into bundles of supply, commonly used for reinforcing bars, bolts and various mechanical parts; Round steel larger than 25 mm, mainly used in the manufacture of machine parts, seamless steel pipe billet, etc.

Classified by chemical composition
Carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel according to its chemical composition (i.e. carbon content).

The difference between round steel and other steel bars

1. The appearance is not the same, the round steel appearance is round, no lines and no ribs, the surface appearance of other steel bars is engraved or ribbed, so that the adhesion of round steel and concrete is small, and the adhesion of other steel bars and concrete is large.
2. The composition is not the same, round steel (first grade steel) belongs to ordinary mild steel, other steel bars are alloy steel.
3. The strength is not the same, the strength of round steel is low, the strength of other steel is high, that is, the diameter of the same round steel compared with other steel bars, round steel can withstand the tension is smaller than other steel bars, but the plasticity of the round steel is stronger than other steel bars, that is, the round steel has a larger deformation before being pulled off, and the deformation of other steel bars is much smaller before being pulled off.
