Incoloy 825 Plates/Bars/Tubes

Incoloy 825 is widely used in industries that require strong resistance to sulfuric acid, phosphoric acid, and other harsh chemicals, as well as excellent mechanical properties at elevated temperatures. Its high nickel content ensures resistance to stress corrosion cracking, while molybdenum enhances resistance to pitting and crevice corrosion in chloride-containing environments.
