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.*INCONEL WELDING ELECTRODE 122 is a highly alloyed product used for joining Inconel alloy 622 (See alloy Digest Ni-382) and similar corrosion resistant grades. In dissimilar welding, it can be used to prevent preferential weld metal attack.
