Product Description

Sae 1045 4140 4340 8620 8640 ASTM Standard Q195/Q235 42crmo steel billet High carbon steel round bar billet

Product Description

ound steel bar is divided into three types: hot rolled, forged and cold drawn. The size of hot rolled round bar is 5.5-250 mm. Among them: small round bars of 5.5-25 mm are mostly supplied in bundles of straight strips, which are often used as steel bars, bolts and various mechanical parts; round bars larger than 25 mm are mainly used for the manufacture of mechanical parts and billets of seamless steel pipes ect. Carbon steel bar can be divided into low carbon steel bar, medium carbon steel bar and high carbon steel bar according to chemical composition (that is, carbon content).
