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.MAYARI R is a low-alloy, high-strength steel having excellent resistance to atmospheric corrosion, high yield point and superior weldability. It may be fabricated with regular shop equipment used for structural-grade carbon steel. It is used widely as a weathering steel in architectural work.
