Mild Carbon Steel Rod Bar Alloy Round Hot Rolled 50M2 Black
Price Hot Rolled / Cold Rolled 10#,20#,30Mn,40Mn,40M2,50M2 Black Mild Carbon Steel Alloy Steel Round Rod Bar
Product Introduction
Carbon steel reinforced: carbon steel bar is made of carbon steel rolling.
According to national standard "technical standards of ordinary carbon structural steel) (GB700-79), the supply of ordinary carbon structural steel in accordance with the manufacturer guarantee condition is divided into the following three categories:
A class of steel - ensure that the mechanical properties of steel; use A for symbols.
B steel - ensure that the chemical composition of steel, with the symbol B said.
Special type of steel - guaranteed both mechanical properties and chemical composition of the steel. Use symbol C said.
The greater the steel grade, the higher the carbon content is, the higher the strength and hardness also, but the plasticity and toughness, cold bending and weldability are reduced.
