Steel is a material with certain shape, size and properties, which is made of ingot, billet or steel through pressure processing. Most steel products are processed by pressure, and the pressure will cause plastic deformation of the processed steel products (billets, ingots, etc.). ). According to the different processing temperatures of steel, it can be divided into cold working and hot working.
