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.JFE produces 11 grades of abrasion-resistant steel plate. This alloy, EH-SP, is made with the emphasis on performance better than conventional plate with a hardness of 500 HB.
