Inconel® Alloy Coil (Inconel 600, 625, 718, etc.)
Engineered for industries requiring continuous high-temperature stability, corrosion resistance, and precision forming, Inconel® alloy coils deliver unmatched performance in aerospace, energy, and chemical processing. With compositions like Inconel 625 (Ni-58%, Cr-22%, Mo-9%), these cold-rolled coils resist oxidation up to 1,200°C (2,192°F), chloride stress corrosion cracking (Cl-SCC), and acidic/alkaline media. Certified to ASTM B168, AMS 5599, and NACE MR0175, they outperform stainless steel with 5x lifespan in aggressive environments while enabling seamless stamping, rolling, and welding.
