Standard ESR Cold Work Tool Steel AISI D2 JIS SKD11 DIN1.2379 Flat Bar
Product Introduction
1.2379 is a high carbon and chromium alloy tool steel, which has high hardness and wear resistance after heat treatment, and has strong hardenability and good dimensional stability.
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
