PM Industries manufactures, supplies, and stocks UNS N05050 Supra 510 Sheet Plate in a range of thicknesses and sizes. Supra 510 is a nickel-based alloy developed for service in corrosive environments where a combination of mechanical strength, pitting resistance, and stability under varying temperatures is required. It's positioned for applications where standard austenitic stainless steels reach their corrosion resistance limits and where the full capability of premium C-family nickel alloys isn't required.

The alloy's corrosion resistance covers a practical range of aggressive environments including chloride-containing process streams, marine atmospheres, and many industrial chemical media. That coverage, combined with useful mechanical properties and adequate fabricability, places Supra 510 in the working zone between high-alloy austenitic grades and the more expensive premium nickel alloys for process equipment and marine applications.

Pitting and crevice corrosion resistance in chloride environments is the key corrosion property for marine, offshore, and chemical process applications. In environments where stagnant zones, crevices at gasket faces, and tube-to-tubesheet joints concentrate chlorides and reduce local pH over time, pitting resistance becomes the determining factor in component service life. Supra 510's resistance to that localized attack form supports longer service intervals between maintenance in those conditions compared to lower-alloy stainless grades.

Fabricability in sheet and plate form covers the operations needed for process equipment construction: plasma or water jet cutting to profile, cold forming into shell or head shapes, fit-up, and welding. With appropriate welding procedures and filler metal selection, Supra 510 produces fabricated assemblies with corrosion resistance maintained through the weld zone.

Sheet and plate are available in a range of thicknesses and sizes with material certification. Contact PM Industries for thickness, width, length, quantity, and pricing.
