Incoloy925/alloy925 is a kind of aging strengthened iron-nickel base alloy. Due to the compound action of chromium, molybdenum and copper in the alloy, Incoloy925/alloy925 alloy has excellent corrosion resistance of reducing chemical media, and good pitting corrosion resistance of crevice corrosion. The nickel content of this alloy is sufficient to ensure its resistance to stress corrosion caused by chloride ions, and it is mainly used in areas requiring high strength and corrosion resistance.
