Because of high strength and high hardness, the elongation rate of HARDOX400 wear resistant steel plate is relatively poor, and the hardness value of HARDOX400 wear resistant steel plate is 370HB-430HB, and the tensile strength is about 1250Mpa. Therefore, the tungsten carbide electrode is generally used to weld HARDOX400 wear resistant steel plate.
It is very important to choose the proper bending radius and the opening of the lower die during the welding process of HARDOX400 wear resistant steel plate. Because the tensile strength of HARDOX400 material is very high, the springback of the material is very strong. When processing, it is necessary to pay attention to safety.
