Characteristics of materials: B steel is aluminum high-speed steel, which mainly adds ,, and B elements to improve hot hardness and wear resistance. Suitable for China's resource situation and low price. The heat treatment hardness can be achieved and the hot hardness is good. However, this kind of steel is easily decarburized by oxidants, and its plasticity and grindability are slightly poor. The usage of high-performance high-speed steel in the international market has exceeded that of ordinary high-speed steel by ~3
