1-866-725-8609Alloy 825 is a nickel-iron-chromium-molybdenum-copper alloy containing high levels of chromium, nickel, copper and molybdenum to provide high levels of corrosion resistance to both moderately oxidizing and moderately reducing environments.
Alloy 825 is a nickel-iron-chromium-molybdenum-copper alloy containing high levels of chromium, nickel, copper and molybdenum to provide high levels of corrosion resistance to both moderately oxidizing and moderately reducing environments. Far superior when compared to the standard stainless steels. As an austenitic, nickel-base alloy, the material is ductile over a wide range of temperatures from cryogenic to well in excess of 1000°F (538°C). Fabrication of Alloy 825 is typical of nickel-base alloys, with the material readily formable and weldable by a variety of techniques.

Alloy 825 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.
Refer to NACE (National Association of Corrosion Engineers) for recommendations
Extra Clean: (XC) Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled”
Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications
Soap (round wire only): Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during customer part forming operation. A soap finish is available in tempered products.
Plated: Many plating options are available.
*Special finishes are available: Contact Ulbrich Wire Sales with special finish and plating requests.
Alloy 825 cannot be hardened using heat treating
For best results refer to: SSINA’s “Welding of Stainless Steels and Other Joining Methods”
