Round steel refers to a solid strip of steel with a round cross section. Round steel is divided into three types: hot rolling, forging and cold drawing.The specification of hot rolled round steel is 5.5-250 mm. Among them: 5.5-25mm small round steel mostly supplies in straight bales, commonly used as reinforcement, bolts and various mechanical parts; Round steels greater than 25 mm are mainly used for manufacturing mechanical parts, blank of seamless steel pipe, etc. Carbon steels can be divided into low carbon steels, medium carbon steels and high carbon steels according to the chemical composition: 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.
