Supreme Steels

D3

Product Description:

D3 is a high-carbon, high-chromium cold-work tool steel known for its exceptional wear resistance, high hardness, and ability to withstand high-stress environments. It is primarily used for manufacturing tools and dies that require superior abrasion resistance and hardness, such as punches, dies, and cutting tools. D3 offers excellent edge retention, making it ideal for applications that demand high precision and durability in harsh working conditions.
