What is the microstructure of spring steel wire rod?

The microstructure of spring steel wire rod is mainly composed of ferrite + pearlite surface decarburization structure. Grains are the basic structural units in steel, usually made up of some atoms arranged in a regular manner. The grain boundary is the boundary area between adjacent grains. Due to the different arrangement of atoms inside the grains, there will be slight deformation at the grain boundary.

When processing spring steel wire rod, the steel is plastically deformed through rolling, crimping and other processes, which will lead to the refinement of grains and the increase of dislocations in the grain boundary area, so that the material shows better elasticity and toughness , and has a higher tensile strength. In addition, spring steel wire rods usually require heat treatment to further improve their mechanical properties and stability. For example, higher hardness and strength can be achieved by quenching and tempering while maintaining a suitable modulus of elasticity.
