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.JESSOP JS Alloy B-2 is a nickel-molybdenum alloy with outstanding corrosion resistance in the as-welded condition. It can be used up to 1000 F and, with proper atmospheric protection, above 1500 F. In the range 1000-1500 F the alloy exhibits reduced ductility and use in that temperature range is to be avoided.
