Property of the low carbon steel

Property of the low carbon steel

The annealed microstructure of the low carbon steel is ferrite and a little pearlite with lower strength and hardness and better plasticity and toughness. Therefore, its property of cold forming is good, and cold forming can be carried out by crimping, bending, stamping and so on. This kind of steel also has good weldability. The low carbon steel with very low carbon content has low hardness and poor machinability and normalizing treatment can improve its machinability.

Emerging uses of low carbon steel

Originally, because of the inherent characteristics of the low carbon steel, its scope of use was greatly limited. With the application of some new technologies in the steel industry in China, many emerging uses of the low carbon steel have been well developed and utilized. At present, some large domestic steel mills or iron and steel trading companies are actively working closely with large domestic slings enterprises to jointly develop a series of rigging products with high technology, high precision and high quality, which has played a good role in promoting technology in the domestic and even global rigging industry. This also shows us a new way of the comprehensive utilization of the low carbon steel.

Mechanical property of low carbon steel

The low carbon steel is a ductile material. The stress-strain curve in tension is mainly divided into four stages: elastic stage, yield stage, strengthening stage and local deformation stage. And there are obvious phenomena of yield and necking in the local deformation stage. In the beginning, it is an elastic stage. It completely follows Hooke's law along the straight line. After the proportional limit, the deformation speeds up, but there is no obvious yield stage.
