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.CARLSON ALLOY C625 has excellent strength and superior resistance to oxidation at temperatures up to 2000 F. Outstanding resistance to general corrosion, pitting, and stress-cracking in many environments. This alloy has exceptional fatigue strength and toughness at cryogenic temperatures.
