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 VNT is a high-strength, low-alloy steel normalized for added toughness, ductility and uniformity. It is a silicon-killed, vanadium-nitrogen treated steel, made to fine-grain practive and provides a 60,000 psi minimum yield strength.
