Learn about high speed steel (HSS), its benefits, advantages, properties, and more in this comprehensive overview.
PM A11 has high chromium content with added vanadium and molybdenum, resulting in a high-speed steel with exceptional wear resistance, deep hardening, and hot hardness. As a CPM steel, PM A11 offers substantially better wear resistance than conventional high-carbon, high-chromium die steels, and work particularly well in cold work tooling applications because of its good grindability and predictable response to heat treatments.
