Product Description

D2 1.2379 SKD11 Hot Forged Special Alloy Steel Flat Bar Round Bar

1. 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. 

2. 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
