D2 die steel characteristics
A good processability, good dimensional stability of heat treatment;
B Excellent machining performance;
C when hardened, it has the best dimensional stability;
D after hardening and tempering, it has high surface hardness and good coordination with the toughness of the body;
It has high wear resistance, hardenability, micro-deformation, high thermal stability and high bending strength, second only to high-speed steel, and is an important material for stamping dies and cold heading dies.
D2 die steel for use
D2 cold work alloy tool steel can be used to manufacture cold work dies with large cross-section, complex shape, large impact force and high wear resistance, such as silicon steel sheet punching die, cold cutting scissors, cutting die, metal stamping die, drawing die, stainless steel sheet punching die, high hardness punching die, rolling die, hardware parts manufacturing and mechanical manufacturing.
