STORA ASP 30 is a high hardenability tungsten-molybdenum alloyed high-speed steel with high cobalt content. It is recommended for cutting tools for hard-to-machine material and high cutting speeds. It has excellent wear resistance, toughness, hot hardness and resistance to tempering. The excellent size stability and good grindability of ASP 30 make it very suitable for tools with a complicated shape. This datasheet provides information on composition, physical properties, microstructure, hardness, and elasticity. It also includes information on forming, heat treating, and machining.
