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.UHB Stainless 44L is a high-strength, corrosion-resistant steel with a duplex structure of about 40% austenite in a ferrite matrix. It is produced with extra-low carbon content for good weldability and good resistance to embrittlement and corrosion induced by carbide precipitation. It has excellent stress-corrosion resistance and an optimum combination of strength and toughness.
