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.Hastelloy B-3 alloy welding products are used to promote similar corrosion resistance to Hastelloy B-3 and B-2 base metals (see Alloy Digest Ni 461 and 249), for the dissimilar welding of Hastelloy B-3 and B-2 to nickel or iron-base corrosion resistant alloys, and for overlay cladding.
