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.CARPENTER STAINLESS TYPE 304HN is essentially a high-nitrogen version of AISI Type 304 stainless steel. By means of solid-solution strengthening, the nitrogen provides significantly higher yield strength and tensile strength as annealed than conventional Type 304, without adversely affecting ductility, corrosion resistance or nonmagnetic properties. Its applications include aircraft and aerospace components and marine hardware.
