Product Details

Incoloy 825®, Nickelvac® 825, Nicrofer® 4221

Known as Inconel 825, Alloy 825 is a nickel iron chromium alloy with small amount of molybdenum, copper and titanium. This combination provides inconel 825 an excellent resistance to various corrosive environments. It has brilliant resistance to reducing and oxidizing acids, to stress-corrosion cracking, as well as to localize attack like pitting and crevice corrosion. Alloy 825 is especially resistant to both sulfuric and phosphoric acids.
