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.PROJECT '70 182-FM is a ferritic free-machining stainless steel designed to have machinability approaching that of AISI Type 416 stainless steel with corrosion resistance comparable to AISI Type 303 stainless steel. It is ideally suited for automatic screw machines and can be used for many of the same applications as Type 303.
