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.HAYNES# Alloy No. 25 is a wrought, high temperature, cobalt-base alloy that has exceptional mechanical properties at temperatures up to 1800 deg. F. in the fully annealed condition without subsequent aging. It is easy to fabricate because it has excellent ductility at room temperature.
