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.STROLOY 787 is an age-hardenable, high-strength, low-alloy steel with excellent low-temperature toughness and weldability. It is suitable for mechanical or pressure tubing applications in most of the tube sizes produced by the manufacturer. It is an excellent choice for fabrication of structural components or for use in pressure tubing subjected to a low-temperature environment.
