Classification of round steel bar
Classified by process Round 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.

Classification by chemical composition 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).

Carbon structural round steel bar application
8#,10#,15#,20#,25# steel is used for machining raw materials into mechanical parts and accessories.
30#-55# It is often used as more important shafts, fasteners, etc.
60# and above belong to high carbon steel, making springs and wear parts.
20CrMnTi is an important carburizing steel, suitable for important gears, etc.
27SiMn is a high-strength, easy-to-weld steel used where welding is important.
35CrMo, 42CrMo are high-strength steels used for very important parts, such as engine connecting rod screws, cylinder head screws. Heavy duty car tire screws, etc.
