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.AVESTA 654 SMO is an austenitic stainless steel which due to its high content of molybdenum and nitrogen possesses excellent resistance to pitting and crevice corrosion. It also has very high resistance to general corrosion in acids, especially those containing halide ions. Furthermore, its mechanical strength is high in comparison with conventional austenitic grades.
