D2 (DIN 1.2379) is a widely used cold work tool steel for shear blades, cutting knives, punches, and wear-resistant tooling parts.
It is known for its high wear resistance and stable performance in cold work applications. D2 is commonly supplied in annealed or heat-treated condition, suitable for small-batch tooling and replacement parts where consistent material properties are required.
