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.Colmonoy 98 was introduced in 1997 and is a patented nickel-base alloy with high corrosion resistance, particularly to sodium hydroxide, salt water, and sulfuric acid. It also has a low coefficient to friction to reduce metal-to-metal adhesive wear loss.
