Inconel 825 Spiral Wound Gaskets
Item No.:ZD-G1206/825
Description:Alloy
825 (UNS N08825) is an
austenitic nickel-iron-chromium
alloy developed for exceptional
corrosion resistance in both
oxidizing and reducing
environments. It was developed
to provide exceptional
resistance to numerous corrosive
environments, both oxidizing and
reducing.
The chromium and molybdenum
content of Alloy 825 provides
resistance to chloride pitting,
as well as resistance to a
variety of oxidizing
atmospheres. It is resistant to
corrosion in a wide variety of
process environments including
sulfuric, sulfurous, phosphoric,
nitric, hydrofluoric and organic
acids and alkalis such as sodium
or potassium hydroxide, and
acidic chloride solutions.

Corrosion
Resistance:
The most outstanding attribute
of Alloy 825 is its excellent
corrosion resistance, in both
oxidizing and reducing
environments, the alloy resists
general corrosion, pitting,
crevice corrosion, intergranular
corrosion and chloride
stress-corrosion cracking.
