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 is a new nickel-molybdenum alloy with thermal stability to reduce the deleterious intermetallic precipitates which cause loss of ductility and corrosion resistance.
