D2 Tool Steel Grade Shapes, Sizes, and Technical Information From Tool Steel Service Inc.
D2 is an air hardening high – carbon high chromium die steel well suited for long run tool and die applications. An abundance of extremely hard, wear, resisting alloy carbide particles imparts excellent abrasion resistance qualities. These carbides are well dispersed resulting in consistent response of the steel during all machining, heat treating, and production operations.

General Characteristics of D2 Tool Steel
|
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. |
