D7 Tool Steel is a high-carbon, high-chromium air-hardening tool steel that exhibits exceptional wear resistance. The high carbon and vanadium contents result in numerous, hard vanadium carbide particles in the steel. These carbides exhibit a hardness that is equivalent to approximately 80 to 85 Rockwell C. Resists wear from sliding contact with other steels as well as from contact with dry and wet slurries of hard abrasive particles such as sand, shot blast media, and ceramics.
APPLICATIONS: Brick mold liners, briquetting dies, shot blasting equipment liners, tools for ceramic extrusion and molding, powder compaction tooling, deep drawing dies, flattening rolls, and machine tool ways.
