SKD11 1.2379 D2 Cold Work Tool Steel Forging Round Bar
1: D2 steel introduction
Cold-work tool steels include the high-carbon, high-chromium steels or group D steels, D2 is the most popular one,these steels all contain 1.5% to 2.35% of carbon and 12% of chromium. 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 the hardened condition.
If customer need better machinability, we recommend A2, because A2 has a chromium content of 5% and is more readily machinable.
