D2 1.2379 SKD11 Cr12Mo1V1 Special Steel Cold Work Tool Steel Die
Steel Alloy Steel Round Bar Machined Surface Stock
Product Introduction
D2 steel is a high wear resistant micro deformation cold working
die steel, belonging to air hardening tool steel. With high quality
fraction of carbon and high chronic, the hardness can up to 60HRC
after heat treatment, but malleability,toughness,rust resistance is
not good and the surface of the steel is also difficult to be
polished.
With the development of cold stamping products moving towards high
accuracy,high efficiency, varieties, we require the mould steel
should has good wear resistance and high toughness.
Compared with Cr12MoV steel, this D2 die steel adds Mo,V
compositions,changed the steel cast structure, improved the
morphology of ledeburite , toughness and wear resistance are better
than Cr12MoV steel, improved the service life as well.Because of
the yield point and plastic deformation resistance is higher than
Cr12MoV steel, so that forging performance and hot molding
properties are a little weak than Cr12MoV steel.
Features
1. High wear resistance
2. High compressive strength
3. Good dimensional stability
4. Good processability
5. Excellent resistance to temper softening
6. Good toughness
