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.ZERON 25 is an alloy developed to combat severe oil field duties where oil, gas, water are contaminated with high levels of chlorides and hydrogen sulfide. The alloy has good mechanical strength and resistance to localized corrosion.
