D2 Tool Steel

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 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 hardened condition.

If you need better machinability then consider A2 tool steel which has a chromium content of 5% and is more readily machinable.
