 According to the use can be divided into carbon structural steel, carbon tool steel. The carbon content of tool steel is between 0.65 and 1.35%. After heat treatment, high hardness and high wear resistance can be obtained. It is mainly used in the manufacture of various tools, cutting tools, molds and measuring tools (see tool steel).

According to the yield strength of steel, carbon structural steel is divided into 5 grades :Q195, Q215, Q235, Q255, Q275

Round steel material :Q195, Q235, 10#, 20#, 35#, 45#, Q215, Q235, Q345, 12Cr1Mov, 15CrMo, 304, 316, 20Cr, 40Cr, 20CrMo, 35CrMo, 42CrMo, 40CrNiMo, GCr15, 65M n, 50Mn, 50Cr, 3Cr2W8V, 20CrMnTi, 5CrMnMo, etc.
