This alloy is almost close to the alloy 800. However, it brings in an improved resistance with regards to issues such as aqueous corrosion. The perfect balance of the alloying elements brings in exceptional resistance for corrosion cracking that comes from chloride stress.
Resistance to cracking from stress-corrosion
Ample resistance to oxidizing and reducing acids
Resistance to attacks such as crevice corrosion or pitting
Resistant to phosphoric or sulfuric acids

Incoloy 825 Key Features:
Oxidization Resistance: The presence of chromium adds resistance to the oxidizing conditions like solutions made from nitrates, oxidizing salts.
Resistance from Corrosion Cracking: The enhanced nickel content helps resist any cracking that occurs due to stress corrosion from chloride ion.
Resistance to Pitting: Titanium within the alloy ensures that the product is stabilized to tackle pitting or intergranular attack post-fabrication.
Resists Acidic Environments: Alloy 825 also has exception corrosion resistance to phosphoric or sulfuric acids.
Incoloy 825 Applications:
Pollution control
Components for chemical processing
