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.VASCO 734 is a precipitation hardening stainless maraging steel. Its corrosion resistance in marine atmosphere is comparable to that of AISI Type 430 ferritic stainless steel. Its low predictable shrinkage reduces post-age machining and eliminates rejected parts due to warpage in heat treatment. The steel is produced by high quality vacuum melting.
