Incoloy 825 plate is a high-performance corrosion-resistant alloy plate manufactured from a nickel-iron-chromium base with additions of molybdenum, copper, and titanium. This alloy offers superior resistance to both oxidizing and reducing environments, including sulfuric and phosphoric acids. Incoloy 825 plates are widely used in chemical processing, marine, pollution control, and oil & gas sectors. Plate factories specialize in hot-rolled and cold-rolled production, typically to ASTM B424 specifications. This article outlines the key features, specifications, and top factories producing Incoloy 825 plate globally, especially in China and India.
