Nickel Alloy 825, Incoloy® 825

Referred to as Nickel Alloy 825, Incoloy® 825 is a nickel-iron-chromium alloy with small amounts of molybdenum, copper, and titanium. This combination gives Incoloy 825 enhanced corrosion resistance in the harshest environments.  Like many of the alloys in the Incoloy family, Incoloy 825 offers users a number of benefits:

  • Excellent resistance to both reducing and oxidizing acids like sulfuric and phosphoric
  • Helps avoid stress-corrosion cracking
  • Stops localized attacks such as pitting and crevice corrosion
  • High level of resistance to variety of oxidizing substances such as nitric acid, nitrates, and oxidizing salt

Because of its superior corrosion resistance characteristics, Incoloy 825 is in use in a number of  industries and applications including:

  • Chemical processing
  • Pollution control
  • Calorifiers
  • Oil and gas recovery
  • Hot vessels for food, water, and seawater
  • Acid production
  • Pickling tank heaters, tanks, and equipment
  • Nuclear fuel reprocessing
  • Radioactive waste handling
  • Marine exhaust systems

Like most of the Incoloy family of alloys, Incoloy 825 has a unique chemical composition which includes:

  • Ni 38-46%
  • Fe 22% min
  • Cr 19-23.5%
  • Mo 2.5-3.5%
  • Cu 1.5-3%
  • Mn 1% max
  • Ti 0.6-1.2%

Incoloy 825 is available via Continental Steel in wide variety of shapes and forms including, pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon, and wire. The various forms of Incoloy 825 meet different critical industrial standards from organizations like ASTM, ASME, BS, SEW, DIN, EN, and ISO.

We stock and sell Nickel Alloy 825 and Incoloy® 825 in Pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon and wire.
