Nickel-chromium superalloys engineered to retain strength and resist oxidation in extreme high-temperature environments above 1000°C, supplied across 600, 601, 625, 718, 800, 825 & 925 with full Mill Test Certification.
Inconel is a family of nickel-chromium superalloys developed to perform in the most extreme environments, resisting oxidation and corrosion at temperatures above 1000°C while retaining mechanical strength. Grade 625 offers excellent fatigue and corrosion resistance, while 718 is precipitation-hardenable for very high strength applications.
Every batch is supplied with complete material traceability and Mill Test Certificates across our full range of tubes, pipes, sheets, plates, bars, rods, wire and flanges.
Stocked across the full Inconel family, each manufactured to its respective ASTM / ASME standard.
