Intro to Nickel Alloys - Incoloy 825 – Alloy 825 – Round Bar – Plate - What is Incoloy?

Описание: Today our topic is another of the alloys in the Incoloy family, Incoloy 825.  Incoloy, like Inconel, is a registered trademark of Special Metals Corporation. For the full transcript, click here:

Other producing mills cannot use the Incoloy name so the generic versions would not use the Incoloy name.  These Incoloy alloys are primarily composed of Nickel, Chromium, and Iron.  Initially Incoloy 825 was developed for  corrosion applications where stainless steels are inadequate and the much higher nickel content Inconel or Monel  alloys a  more costly solution.

Alloy  825  contains additions of Molybdenum and Copper for enhanced corrosion resistance in reducing environments while the Nickel and Chromium contents provide resistance to oxidizing environments.   Alloy 825 is a fully austenitic solid solution and cannot be strengthened by heat treatment. Cold work can increase strength.

Applications include all sorts of components in pollution control, chemical, and petrochemical processing equipment and it is suitable for both oxidizing or reducing environments. NACE approved for sour service environments.  It also resists chloride and pitting corrosion in sea water.

Incoloy 825 is typically limited to applications less than 1000° F and below where strength is an issue.  Exposure to higher temperatures can result in a loss of ductility and impact properties.
