D2 tool steel bar is an air-hardening, high carbon, and high chromium tool steel, heat treatable to HRC 60-62. D2 is widely used in cold work applications requiring very high wear resistance. It offers excellent abrasion resistance and compressive strength combined with mild corrosion resistance and moderate toughness. It is very deep hardening and shows good dimensional stability after proper treatment. D2 can be supplied in many finishes including, hot rolled, part pre-machined, and fine machined condition.

FED QQ-T-570 and SAE J437 are comparable materials used in D2 Round Bars. Die-making for production lines back then utilized D2 steel.
