UNS N06625 / W.Nr. 2.4856 | ASTM B443, B446, B444 | MTC, Traceability & Export Packing Available
Inconel 625, also known as Alloy 625, UNS N06625 or W.Nr. 2.4856, is a nickel-chromium-molybdenum-niobium alloy designed for high strength, excellent corrosion resistance and reliable performance in harsh industrial environments.
Voyage Metal supplies Inconel 625 in multiple product forms, including plate, sheet, pipe, tube, round bar, flat bar, wire, strip, forgings and fittings. Materials can be supplied with Mill Test Certificate, EN 10204 3.1, heat number traceability and export packing.
Buyers comparing nickel alloys can also review the Inconel 718 vs 625 comparison and the latest Inconel price chart and 2026 buying guide before confirming the final material plan.
Excellent resistance to pitting, crevice corrosion and chloride-containing environments.
Alloy 625 offers good weldability and fabrication performance for many industrial components.
Used in marine, chemical processing, oil and gas, aerospace, power generation and high-temperature systems.
Inconel 625 can be supplied in standard sizes or custom dimensions according to project requirements. Cutting, special length supply and export packing are available upon request.
