What is the difference between Inconel 825 and INCOLOY 825?
Incoloy is a registered trademark of Specialty Metals Corporation for a family of nickel-based alloys primarily alloyed with chromium. There are currently over a dozen different grades in the Incoloy range, but one of the most widely known is Incoloy 825.
Incoloy 825 was launched on the market in 1952 and was based on Incoloy 800 and had better resistance to sulfuric acid. For many years it was the default metal of choice for handling sulfuric acid. The high nickel content ensures resistance to stress corrosion cracking and has a wider operating temperature range than many stainless steels.
Inconel and Incoloy are two different families of nickel-based alloys originally developed by Specialty Metals Corporation (which owns the Inconel and Incoloy trademarks). There is no such thing as an Inconel 825.
Inconel grades are nickel-based alloys, again primarily alloyed with chromium. However, they typically have a much higher nickel content than Incoloy grades, providing improved performance at higher temperatures while retaining more strength.
