JISG3106 SM400A carbon steel plate classification

JISG3106 SM400A carbon steel plate is classify by chemical composition, JISG3106 SM400A carbon steel plate is divided into low carbon, medium carbon and high carbon steels.
The low carbon steel and mild steel, carbon content from 0.10% to 0.30% low carbon steel is easy to accept all kinds of processing such as forging, welding and cutting, commonly used in the manufacture of chains, rivets, bolts, shaft etc.

SM400A carbon steel plate, carbon content of 0.25%~0.60%. There are many kinds of products, such as killed steel, semi killed steel and rimmed steel. In addition to carbon, it also contains a small amount of manganese (0.70%~1.20%). According to the quality of products are divided into ordinary carbon structural steel and high-quality carbon structural steel. The heat treatment and cutting performance are good, and the welding performance is poor. Strength and hardness are higher than those of low carbon steel, while plasticity and toughness are lower than those of low carbon steel. Without heat treatment, direct use of hot rolled wood, cold drawn material, can also be used after heat treatment. The quenched and tempered medium carbon steel has good comprehensive mechanical properties. The highest hardness reached is about HRC55 (HB538), and sigma B is 600~1100MPa. Therefore, the medium carbon steel has the most extensive application in the medium strength level. Besides being used as building material, it is widely used in the manufacture of various mechanical parts.

SM400A carbon steel plate, the high carbon steel is often called tool steel, carbon content from 0.60% to 1.70%, can be hardened and tempered. A hammer, by 0.75% carbon content steel; cutting tools such as drills, taps, reamers, made of carbon steel 0.90% to 1%.
