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 Polarit 317LMN is a low-carbon, higher-molybdenum austenitic steel frequently used for flue gas desulfurization service. The alloy is a fully austenitic stainless steel with excellent resistance to corrosion in chloride environments and nonoxidizing acids. It is significantly stronger than most low-carbon stainless steels and its structural stability makes for good weldabillity.
