There are many types of molds, and the performance requirements of various types of molds are also different. What are the main performance indicators of hot mold materials?
1 Room temperature hardness, high temperature hardness
2 Room temperature tensile strength, high temperature tensile strength
3 Room temperature impact toughness, high temperature impact toughness
4 hot and cold fatigue resistance, fracture toughness
In addition, hot work mold materials have special properties:
(1) Thermal stability of hot die materials
(2) Tempering stability of hot work die materials
(3) Thermal fatigue resistance and fracture toughness of hot die materials
(4) High temperature wear and oxidation resistance of hot die materials
All kinds of hot work mold material performance requirements:
(1) Hammer forging die hot work die material: high high temperature strength and toughness, good wear resistance, but also the requirements of hot and cold fatigue and mechanical fatigue resistance. In addition, the size of the hammer forging die is relatively large, and it requires that the hammer forging die steel has high hardenability.
(2) Hot extrusion die hot work die material: It has high thermal stability, high high temperature strength and sufficient toughness, good thermal fatigue resistance and high wear resistance.
(3) Die casting mold hot work mold materials: high heat resistance and good high temperature mechanical properties, excellent thermal fatigue resistance, high thermal conductivity, good oxidation resistance and corrosion resistance, high hardenability Wait.
(4) hot stamping die hot work mold material: lower operating temperature, should have high wear resistance, good toughness and processing technology performance.
