| TLS A7 Mod. is a chromium-modified A7 type 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. TLS A7 Mod. tool steel 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. Typical applications include brick mold liners, sand slinger liners, shot blasting equipment liners, extrusion tools for ceramics, powder compaction tooling, and machine tool ways.
