Material of Tungsten Steel Punch


Depending on the material and thickness of the punching needle, different tungsten steels should be selected. Generally, the thicker the punched product, the lower the hardness and the better the toughness of the tungsten steel should be selected. The harder the material, the tungsten steel should choose a slightly lower hardness model, which can effectively prevent the punching needle from being punched out. For punching relatively thin plates, or those with low hardness, tungsten steel punching needles can be used with higher hardness for hole processing of this product, which can improve the service life of punching needles.
