Basic Information

D3 TOOL & DIE STEEL

Product Overview

D3 TOOL & DIE STEEL is a premium high-carbon, high-chromium air-hardening tool steel, renowned for its exceptional abrasive wear resistance and high compressive strength. Containing 12% chromium, it forms an extremely high volume of hard carbides, making it the premier choice for long-run tooling applications where maintaining a sharp cutting edge is critical. D3 offers superior dimensional stability after heat treatment, ensuring high precision for complex die designs operating under extreme mechanical stress.
