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.JESSOP JS17Cr-7Ni is a semi-austenitic precipitation-hardening steel. Its composition gives it a unique and attractive combination of corrosion resistance, cold formability, high strength and hardness, excellent fatigue properties and minimum distortion upon heat treatment. Typical applications include aircraft structural members and equipment for the process industries.
