Incoloy 825 (For Springs)
Incoloy 825 is a Nickel-Iron-Chromium alloy with additions of Molybdenum and Copper. It has excellent resistance to both reducing and oxidising acids, to stress-corrosion cracking and to localised pitting and crevice corrosion.It is also especially resistant to sulphuric and phosphoric acids.
Incoloy 825 is also known as Nicrofer 4221, Superimphy 82 and Ferrochronin 825.
