Description:

It is the most widely used and most representative hot work die steel. It has good comprehensive performance at medium temperature, high hardenability and high toughness, excellent thermal cracking ability, and resistance to softening at higher temperatures. Ability, low heat treatment deformation rate, medium wear resistance, strong cutting ability, widely used in the production of important components and mold structural materials in the aviation industry.
