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 Alloy G-3 is a nickel-base alloy with outstanding corrosion resistance in the as-welded condition. It is an improved wrought version of HASTELLOY Alloy G. Alloy G-3 has the same excellent general corrosion resistance as Alloy G, along with improved resistance to heat-affected zone (HAZ) attack and excellent weldability. Alloy G-3 is a logical choice for many chemical applications, particularly those involving sulfuric and phosphoric acids, as well as applications where Alloy G has been used successfully.
