Inconel 625 Spiral Wound Gaskets
Item No.:ZD-G1206/625
Description:Alloy
625 (UNS N06625) is an
austenitic nickel base
superalloy possessing excellent
resistance to oxidation and
corrosion over a broad range of
corrosive conditions. Even
temperature to 1100 degree C,
alloy 625 also has exceptional
fatigue resistance.
The material possesses a high
degree of formability and shows
better weldability than many
highly nickel-base alloys. The
alloy is resistant to
intergranular corosion even in
the welded condition.

Corrosion and
Oxidation Resistance:
The high level of chromium and
molybdenum in Alloy 625 provides
a high level of pitting and
crevice corrosion resistance to
chloride contaminated media,
such as seawater, neutral salts,
and brines;
Tests in geothermal brines
indicate Alloy 625 is highly
resistant to hot geothermal
fluids comparable to Titanium
Grade 2;
Tests in simulated flue gas
desulfurization environments
show Alloy 625 highly resistant
to the environment in comparison
to alloys such as Alloy 316 AND
Alloy 276.
