Steel Round Bar

Description

Round steel rod is a kind of multi-functional light steel, which plays an important role in modern industry. Our company advanced production equipment, can supply all kinds of specifications of steel bars, round steel, square steel, flat steel and so on.

Product Description

Round steel refers to a solid long steel bar with a circular cross-section.
Round steel is divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled round steel are 5.5-250 mm. Among them: small round steel of 5.5-25 mm is mostly supplied in straight strips and bundles, and is commonly used as steel bars, bolts and various mechanical parts; round steel larger than 25 mm is mainly used to manufacture mechanical parts and seamless steel pipe blanks. wait.
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).
Round steel material: Q195, Q235, 10#, 20#, 35#, 45#, Q215, Q345, 12Cr1Mov, 15CrMo, 304, 316, 20Cr, 40Cr, 20CrMo, 35CrMo, 42CrMo, 40CrNiMo, GCr15, 65Mn, 50Mn, 50Cr, 3Cr2W8V, 20CrMnTi, 5CrMnMo, etc.
