Product features

This steel has been annealed, heating the steel to the appropriate temperature for a certain period of time and then slowly cooling. The hardness of the annealed steel is reduced and the plasticity is greatly improved, which is advantageous for cutting and cold deformation processing about steel. In addition, in the annealed steel, the crystal grains are refined, the structure and composition of the steel become more uniform, the properties thereof are well improved, and the subsequent heat treatment of the steel is facilitated. In addition, the annealing treatment also eliminates the internal stress in the steel, which makes the steel free from deformation or cracking.
