D2 Steel Properties
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 you need better machinability then consider which has a chromium content of 5% and is more readily machinable.
Typical applications for D2 Steel:
Forging:
Heat slowly and uniformly to 700°C then more rapidly to 900/1040°C. Do not continue to forge D2 below 925°C. Reheat as often as necessary to maintain proper forging temperature. After forging cool slowly. This is not an annealing process. After the forging is cold, it must be annealed as described below.
Annealing:
Heat uniformly to 843/871°C, then slow furnace cool at a rate of not more than 10°C per hour. After annealing D2 a maximum hardness of 240 Brinell may be achieved
Hardening:
D2 tool steel is extremely sensitive to overheating during hardening – do not overheat.
Pre heat slowly to 750/780°C and soak. Continue heating to the final hardening temperature of 1000/1030°C and allow the component to equalise. Quench in oil or cool in air.
Tempering:
Heat uniformly and thoroughly to the desired temperature and hold for 25 minutes per cm of thickness. D2 can be double tempering at approximately 15°C below the first tempering, after intermediate cooling to room temperature.
