View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.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.
