This kind of Cold-finished Steel refers to cold drawing of the steel bar at normal temperature to increase the yield point of the steel bar, thereby increasing the strength of the steel bar and achieving the purpose of saving steel. It pulls the smooth steel bar strongly at normal temperature, and makes it pass through the special tungsten alloy wire drawing die hole to make the steel bar thinner, produce large plastic deformation, and improve the strength.
After the stress of the reinforcing bar exceeds the yield point, the internal lattice of the reinforcing bar slides along the crystal plane, and the crystal lattice is distorted and deformed, which changes the internal structure of the reinforcing bar, thereby improving performance. The Cold-finished Steel is widely used in automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, canned food, etc. It receives an excellent reputation among customers due to high quality.
