Alloy 825 • UNS N08825 • WNR 2.4858

Description

Alloy 825 (UNS N08825) is an austenitic nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. It was developed to provide exceptional corrosion resistance in both oxidizing and reducing environments. The alloy 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 alloy resistant to intergranular attack after exposure to temperatures in a range that would sensitize unstabilized stainless steels. The fabrication of Alloy 825 is typical of nickel-base alloys, with material being readily formable and weldable by a variety of techniques Available tube product forms Straight Coiled Seamless Seam welded and cold redrawn Seam welded, cold redrawn and annealed Typical Applications C ondensers Oil and gas well equipment Hydraulic systems Chemical injection lines Chemical process equipment and vessels Downhole control lines Control and...
