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.SPECIAL HS -55 is a hot-work tool and die steel of the 18-4-1 type of high-speed steel with lower carbon content for applications in which higher hardness must be maintained at elevated temperatures. It has a high degree of toughness and resistance to softening.
