D2 is perhaps the most common cold work die steel used the World over. It is a high carbon 12% chrome material that is regularly used in applications where high wear resistance and good toughness are required. D2 has also been succesfully used in plastic mold applications. D2 is widely available in Plate, Block, Round bar, Groundstock, and Drill Rod forms and offers high wear resistance, good stability, good compressive strength, and good hardenability. The optimal hardness range is 56-62 HRC.
