The material selection of punch is mainly high-speed steel. The commonly used materials include Japanese SKH9, SKH55, SKH59 and American M2, M35 and M42.The main characteristic of the material is that the material can maintain good red hardness during high-speed upsetting, and the wear resistance is also very good, and can ensure a certain toughness.
The choice of the header punch material is the key step, followed by the surface coating, to improve the high temperature resistance and wear resistance of the header punch, so as to achieve the best use effect and the longest life of the header punch.
