Incoloy 825 Nipple

Incoloy 825 Concentric Swaged Nipple is an austenitic nickel – iron – chromium alloy with additions of molybdenum, titanium and copper, where the nickel content is sufficient for resistance to chloride – ion stress – corrosion cracking. Although not fully resistant to stress – corrosion cracking in boiling magnesium chloride, Incoloy 825 Eccentric Swaged Nipple has good resistance in neutral chloride media.

Incoloy 825 Nipple also has good resistance in neutral chloride media, stress – corrosion cracking and satisfactory resistance to pitting and crevice corrosion. Alloy 825 Nipple is characterized by high resistance to chloride – induced stress corrosion. Alloy 825 Hexagon Nipple is a grade that consists mainly of Nickel, Chromium and Iron but also contains Copper, Titanium and Molybdenum, and that composition provides excellent resistance to an array of corrosive environments.
