Inconel® Alloy Plate (Inconel 600, 625, 718, etc.)
Engineered for industries demanding extreme thermal stability, corrosion resistance, and mechanical strength, Inconel® alloy plates are nickel-chromium superalloys optimized for aerospace, energy, and chemical processing. With compositions like Inconel 625 (Ni-58%, Cr-22%, Mo-9%), these plates resist oxidation up to 1,200°C (2,192°F), chloride stress corrosion cracking (Cl-SCC), and sulfuric/phosphoric acid attack. Certified to ASTM B168, AMS 5599, and NACE MR0175, they outperform stainless steel by 5x lifespan in aggressive environments.
