SB 423 UNS N08825 Incoloy 825 Nickel Iron Chromium Austenitic Alloy Stainless Steel Pipe
Incoloy 825 Nickel iron chromium austenitic alloy Stainless Steel Pipe 2.4858 / UNS N08825
Material Description:
Incoloy 825 (UNS N08825) is a nickel-iron-chrome austenitic alloy with added molybdenum, copper, and titanium. Special corrosion resistance in oxidizing and reducing environments.
Compared with ordinary austenitic stainless steel, nickel in alloy 825 makes it resistant to chloride stress corrosion, and molybdenum and copper make it have relatively strong corrosion resistance in a reducing environment.
