Explanation

It is suitable for making tool steel for various moulds. Mold forming processing has the characteristics of good product quality, stable performance, uniform size, and high production efficiency, and is an important minimally cutting and non cutting processing process in the mechanical processing industry. The output of die steel accounts for more than 80% of the output of tool steel. The mold industry has become an important sub industry of modern industry. The quantity and quality of mold production has become an important indicator to measure the degree of industrialization. die steel can be used to manufacture cold stamping die, hot forging die, die-casting die, etc. die steel shall have high hardness, strength, wear resistance and appropriate toughness. According to different die working environments, it also requires excellent high temperature strength, red hardness, thermal fatigue, thermal conductivity and corrosion resistance. According to the use properties of die steel, it can be divided into three categories: one is cold work die steel that deforms metal in cold state, the second is hot-working die steel that deforms metal in hot state, and the second is die steel for plastic materials forming.
