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 5C is a high yield strength alloy steel that is furnished in the water quenched and tempered condition. It is used where good weldability, ductility and toughness are required. It can be welded readily by prescribed are welding procedures and is used in a variety of welded structures such as crane booms and portable drilling rigs. It is supplied as tubing and shapes; for details see Forms Available.
