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 A-2 is a high-hardenability cold-work tool and die steel with excellent non-deforming properties. It is air hardening and therefore exhibits a high degree of dimensional stability in heat treatment. It is recommended where the application requires a good combination of machinability, wear resistance and toughness. Among the many uses of Guterl A-2 are shear blades, blanking and forming dies, punches and burnishing tools.
