General Characteristics |
A high carbon, high chromium type tool steel, D2 combines exceptional wear resisting properties with maximum toughness at high hardness in sections of all sizes. Minimum tendency to distort during heat treatment makes D2 popular where intricate die designs are involved, or in any application requiring extreme stability during heat treatment. D2 is widely used in long run, high production applications where long die life is desired. |
Typical Applications |
Forming rolls, thread rolling dies, blanking dies, trim dies, shear blades, fine blanking tools, feed screws, Industrial Knives, Slitters. |
