    Our D2 steel is manufactured from British and European raw materials, ensuring a product that you can trust. Compared to other cold work tool steels, D2 boasts a much higher resistance to wear, thanks in part to its increased vanadium content. And with its high carbon content, D2 offers excellent corrosion resistance once the steel has been hardened.


    But what really sets D2 apart from other steels is its popularity. As part of the D group of steel, which includes D3, D4, D5, and D7, D2 is by far the most widely used 12% high chromium tool steel on the market today.

    Forging and Annealing

    When it comes to forging D2 steel, it’s important to pre heat slowly and evenly to 700°C before slowly heating it to the recommended forging temperature of 925 – 1040°C. And when annealing D2, make sure to raise the temperature to 843 – 871°C and cool at a rate no faster than 10°C per hour to room temperature.


    Before forging, D2 should be heated at an even temperature until 700°C. After, proceed to heat slowly to a temperature of 925 – 1040°C and proceed with forging. If the temperature falls, please reheat to the proper forging temperature and cool slowly.


    Hardening and Tempering

    To harden D2 steel, pre heat it slowly to 750 – 780°C before increasing the final hardening temperature to 1000 – 1030°C and letting the tool steel equalize. Then, quench in oil or cool in the air for maximum hardness. To improve wear resistance and abrasion, temper the steel to the desired temperature and hold for 25 minutes per cm of thickness.
