Inconel 625 Foil Strips
Inconel 625 is a high-performance nickel-chromium alloy known for
its excellent strength and resistance to oxidation and corrosion.
What are the corrosion-resistant properties of Inconel 625?
1. Oxidation Resistance:
Inconel 625 forms a stable oxide layer at high temperatures, which
protects the underlying metal from further oxidation.
2. Pitting and Crevice Corrosion Resistance:
The alloy's high chromium content provides excellent resistance to
pitting and crevice corrosion, particularly in chloride
environments.
3. Stress Corrosion Cracking (SCC) Resistance:
Inconel 625 is highly resistant to stress corrosion cracking, which
is crucial in applications involving high tensile stresses and
corrosive media.
4. General Corrosion Resistance:
It demonstrates remarkable resistance to a wide range of corrosive
environments, including acids, alkalis, and saltwater.
5. Biocompatibility:
Inconel 625 is often used in medical applications due to its
biocompatibility and resistance to corrosion in body fluids.
6. High-Temperature Corrosion Resistance:
It maintains its corrosion resistance at elevated temperatures,
making it suitable for applications in gas turbines and other
high-heat environments.
These properties make Inconel 625 a preferred choice for industries
like aerospace, chemical processing, and marine, where corrosion
resistance is critical.
