Mild Steel Full Thread Hardening Treatment Welding Pin.
Description
Welding pin is a kind of high-strength rigid connection fasteners. Welding pins are cylindrical heads for arc stud welding, which is short for Cheese head studs for arc stud welding. The specifications of welding pins are nominal diameter Ф10～Ф25mm. The length is 40～300 mm. Welding pins have the manufacturer's identification mark made by embossing on the top surface of the head, and the welding pins have a wide range of uses.
Hardening effect of Mild steel
When steel is cooled quickly from high temperature, ferrite scrapes carbon and nitrogen is supersaturated, and it can slowly form iron carbonitride at room temperature, so the strength and hardness of steel increase, while plasticity and toughness decrease.
It also can Increased yield stress, decreased toughness.
The processing of metal materials at room temperature or below the recrystallization temperature produces strong plastic deformation, which causes the crystal lattice to be distorted and distorted, the crystal grains are sheared, slipped, and the crystal grains are elongated. These will increase the hardness of the surface layer metal and reduce it. The plasticity of surface layer metal deformation is called cold work hardening. In the cold plastic deformation of the metal, the strengthening index of the metal, such as the yield point, hardness, etc., is increased, and the phenomenon that the plastic index such as the elongation decreases is called hardening.
