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.Remanit 4511 was developed as a modification of Type 430 to improve its aqueous corrosion resistance. Due to its composition, that is, an addition of niobium (columbium), the alloy maintains better corrosion resistance in welds and heat-affected zone areas than does Type 430.
