Tool Steel (D2)

Grade Introduction:

D2 steel is an air-hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion-resistant properties. It is heat treatable and will offer a hardness in the range of 55-62 HRC, and is machinable in the annealed condition. D2 steel shows little distortion on correct hardening. D2 steel’s high chromium content gives it mild corrosion-resisting properties in the hardened conditions.

A high carbon high chromium tool steel grade offering very high wear resistance and toughness. D2 tool steel hardens in air with a low order of movement and offers a measure of corrosion resistance when polished. Commonly used for tools operating under conditions of severe wear and abrasion or as an alternative to oil hardening tool steel grades when long runs are required.

Supplied Condition:

Hot Rolled

Grade Applications:

Typical applications for D2 Steel:
Stamping or Forming Dies, Punches, Forming Rolls, Knives, slitters, shear blades, Tools.

Annealing:

D2 is supplied in the annealed and machinable condition. Re-annealing will only be necessary if the steel has been forged or hardened by the toolmaker. To anneal, heat slowly and uniformly to 900°C. Soak for three to four hours and allow to cool in the furnace to room temperature. Re-heat to 800-1040°C and again soak for three to four hours. Allow cooling in the furnace to room temperature.
