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.CRUCIBLE 416 PLUS is a hardenable chromium steel with improved machinability and non-galling characteristics. Better machinability than that of standard AISI Type 416 stainless is obtained by the use of balanced chemistry and special manufacturing techniques. This grade is magnetic in all conditions. Typical applications are screw-machine products and all machined parts requiring good corrosion resistance.
