There are many types of argon arc welding wires for moulds, such as SKD11, SKD61888T, P20Ni, etc. KD11>0.5~3.2mm HRC 56~58 welding repair cold steel, metal stamping die, cutting die, cutter, forming die, and argon welding rod with high hardness, wear resistance and high toughness for hard surface of workpiece. Before welding repair, heat and preheat, otherwise cracking is easy to occur.
