General Proprieties
Alloy 725 (UNS N07725) is useful for a range of applications that require outstanding corrosion resistance along with high strength. The alloy is used for hangers, landing nipples, side pocket mandrels and polished bore receptacles in sour gas service, where it resists the effects of hydrogen sulfide, chlorides and carbon dioxide. The alloy is also attractive for high strength fasteners in marine applications, where it resists corrosion, pitting and crevice attack in sea water. This alloy is also know as Inconel® 725, Chronin® 725, Altemp® 725 and Nickelvac® 725. Alloy 725 is available at CHUN & VOLLERIN in these formats: Bars.
