Tool steel D2

4.9 (9 Reviews) 36 orders

Material type: Metal, High hardness, High strength

Tool Steel D2 is a versatile high-carbon, high-chromium, air-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials. Although other steels with improved toughness or improved wear resistance are available, D2 provides an effective combination of wear resistance and toughness, tool performance, price, and a wide variety of product forms.

Material advantages

D2 steel is perfectly suited for long lasting tools and die applications. It provides excellent abrasion resistance qualities, very high hardness and mild corrosion resistance in the hardened state and good machinability in the annealed state.

Material shortcomings

Poor weldability.
