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.HWD No. 3 is an air-hardening hot work steel recommended for dies where a minimum amount of distortion during hardening is required. It is equivalent to AISI Type H13.
