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.ARMCO FORMABLE 50 HR is a hot-rolled high-strength low-alloy steel that provides excellent ductility, weldability and edge-tear resistance at a minimum yield strength of 50,000 psi (345 MPa). It has unusually good fabricating properties that are the result of closely controlled processing of a fully killed, low-carbon, vacuum-degassed, columbium-alloyed steel. This special composition and processing practice minimize harmful nonmetallic inclusions that hamper formability. Typical applications include automotive, construction and farm-equipment components.
