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.GUTERL S-5 is a shock-resisting steel recommended for severe and repeated impacts in service. It has an excellent combination of toughness and hardness to survive the high stresses in service and to resist abrasion and wear. It is normally hardened by austenitizing and quenching in oil but it can be water quenched successfully with proper precautions. Its many uses include hammers, hand chisels, boiler punches, shear blades and pneumatic tools.
