Die steel die steel is a steel used to make molds such as cold die and hot forging die. Molds are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances. The quality of the mold directly affects the quality of the pressure processing technology, the precision production and production cost of the product, and the quality and service life of the mold are mainly affected by the mold material and heat treatment, in addition to reasonable structural design and processing accuracy.
       
  Features of die steel: 1. Strength properties 2 toughness 3. Wear resistance 4. Resistance to thermal fatigue 5. Occlusal resistance

Its more applicable scope can be divided into the following categories:
1 cold work die steel
2. High carbon low alloy cold work die steel
3 anti-wear cold work die steel
.4 impact resistant cold work die steel
5 cold work die carbon tool steel
6 high speed steel for cold work die
7 non-magnetic mold steel
8 high heat resistance hot work die steel
9 plastic mold steel
10 carbon plastic mold steel
11 age hardening plastic mold steel
12 corrosion-resistant plastic mold steel
