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.TECHALLOY 17-7 PH is a precipitation-hardenable high-strength stainless steel with excellent fatigue properties, good resistance to corrosion, minimum distortion on heat treatment and excellent spring characteristics. Its highest tensile strength and hardness are produced by starting with soft, solution-treated (annealed) material, cold working and then precipitation hardening at 900 F (Condition CH900); in this condition its elastic properties are similar to the best alloy spring steels.
