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.Inco-Weld C-276 (ERNiCrMo-4) is a NiCrMo filler metal with increased molybdenum, tungsten, and reduced niobium and is suited to both gas metal arc welding (GMAW) or gas tungsten arc welding (GTAW) processes, either manually or fully automated. The alloy offers strength levels consistently exceeding the minimum requirement of the 9% Ni steels, excellent Charpy impact toughness at -196 C (-321 F), and improved wire delivery to the weld pool resulting from controlled filler metal processing.
