D2 is a tool steel with a carbon content of 1.5%, a chromium content of 11.5%, and a hardness of up to 60HRC after heat treatment. It is a 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 kind of steel that is more suitable for practical use. Bob Dozier likes to use D-2. D2 steel is highly wear-resistant, slightly deformed cold work die steel, wind-hardened tool steel. D2 steel can be used to manufacture cold work die steels with large cross-sections, complex shapes, high impact resistance, and high wear resistance, such as silicon steel sheet die, cold cutting scissors, trimming die, etc.

D2 The high carbon and high chromium cold work die steel widely used internationally is a ledeburite steel with high hardenability, hardenability and high wear resistance; good high temperature oxidation resistance, rust resistance after quenching and polishing Good capacity, small heat treatment deformation.

Suitable for tool steels with complex and possible deformations, various cold stamping dies with high wear resistance and long life, cold cutting blades, thread rolling plates; cold extrusion forming, drawing dies, stainless steel sheets and high hardness materials. Mode etc.
