Description
D2 steel is a kind of ledeburite tool steel, which is the most available and popular among D-series tool steels. Its hardness can reach 60+HRC after heat treatment. The material contains up to 1.6% carbon and 13% chromium, so it’s also known as semi-stainless steel, but the high chromium content is not enough to provide the corrosion resistance of stainless steel because much of the chromium is incorporated in alloy carbides. It is deep hardening with low distortion and high safety in hardening. It also has high resistance to softening and medium resistance to decarburizing and it is easy to nitridize. D2 tool steel has high wear resistance and good toughness and is therefore known as the blade steel. The following tables show D2 tool steel properties including chemical composition, physical and hardness, etc. D2 tool steel chemical composition is listed in the following table.
