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.UNS No. G10780 is a plain carbon steel; it has low hardenability and a high carbon content (nominally 0.78%). It can be hardened by quenching into oil or water from the austenitizing temperature; care must be exercised to prevent cracking when quenching into water. This steel develops high surface hardness and a soft core on quenching and tempering lightly. It has good wear resistance. Its many uses include agricultural equipment, tools, springs, and machinery parts.
