D2 is a tool steel with a carbon content of 1.5%, a chromium content of 11.5%, and a hardness of 60HRC after heat treatment. It is a kind of semi-stainless steel. D2 steel has good wear resistance and moderate toughness. The disadvantage is that the corrosion resistance is slightly insufficient. It is a more suitable steel for practical use. Bob Dozier likes to use D-2. D2 steel is high wear-resistant, micro-deformation cold work die steel, air-hardened tool steel. D2 steel can be used to manufacture cold work die steel with large cross section, complex shape, high impact force and high wear resistance, such as silicon steel sheet die, cold cutting scissors, trimming die, etc.

D2 is a high-carbon and high-chromium cold work die steel widely used in the world. It is a ledeburite steel with high hardenability, hardenability and high wear resistance. It has good high temperature oxidation resistance and is resistant to rust after quenching and polishing. Good ability, small heat treatment deformation.
