1.3343die steel
Detailed Introduction：

Characteristics and Scope of Application：

 It is the representative steel grade of tungsten molybdenum universal high-speed steel. This steel has the advantages of fine and uniform carbides, high toughness, and good thermoplasticity& emsp; It is a high alloy steel containing multiple alloying elements, belonging to the Lai type steel. It has high hardness, high wear resistance, high thermal hardness, high hardenability, and sufficient plasticity and toughness, as well as good casting, forging, welding, and mechanical processing properties. Therefore, it occupies an important position in tool steel
