Low-carbon steel, with a carbon content of 0.10% to 0.30%, is easy to accept various processing such as forging, welding and cutting. It is often used to make chains, rivets, bolts, shafts, etc. High-quality low-carbon steel is rolled into thin plates to make deep-drawn products such as automobile cabs and generator covers; it is also rolled into bars to make mechanical parts with low strength requirements.
Medium carbon steel is a carbon steel with a carbon content of 0.25% to 0.60%. In addition to carbon, it can also contain a small amount of manganese. Medium carbon steel has good thermal processing and cutting performance, but poor welding performance. Strength and hardness are higher than low carbon steel, while plasticity and toughness are lower than low carbon steel. Hot-rolled and cold-drawn materials can be used directly without heat treatment, or medium carbon steel can be used after heat treatment. Medium carbon steel is widely used in the construction sector.
High carbon steel has a carbon content of 0.60% to 1.70% and can be hardened and tempered. It has poor thermal conductivity and is more sensitive to quenching. High carbon steel is more prone to hot cracks when welding than medium carbon steel.
