China 825 Nickel Alloy Tube

China 825 (UNS N08825) Nickel Alloy Tube is an austenitic nickel-iron-chromium alloy pipe with additions of molybdenum, copper, and titanium. China 825 Nickel Alloy Tube has outstanding resistance to numerous corrosive environments. Moreover, it also includes outstanding resistance to both decreasing and oxidizing acids, to stress-corrosion cracking, also to localized attacks for example pitting and also crevice corrosion. China 825 Nickel Alloy Tube is utilized for chemical processing, pollution-control tools, oil and also gas well piping, nuclear fuel reprocessing, acidity production, and also pickling tools.

China 825 Nickel Alloy Tube is a nickel-iron-chromium alloy with inclusions of molybdenum and also copper. It is resistant to chloride stress-corrosion cracking and pitting. The addition of titanium stabilizes Alloy 825 against sensitization in the as-welded condition making the China 825 Nickel Alloy Tube resistant to intergranular attack after exposure to temperatures in a range that would sensitize unstabilized stainless steels. The fabrication of China 825 Nickel Alloy Tube is typical of nickel-base alloys, with the material being readily formable and weldable by a variety of techniques.


Features of China 825 Nickel Alloy Tube

● Excellent resistance to decreasing and also oxidizing acids

● Good resistance to stress-corrosion cracking
