400 Spiral Wound Gaskets
Item No.:ZD-G1202/400
Description:
Alloy 400 ( UNS N04400) is a
nickel-base alloy with
resistance to a variety of
corrosive conditions. The alloy
is most frequently specified in
environments ranging from mildly
oxidizing through neutral and in
moderately reducing conditions.
An additional application area
of the material is in marine
environments and other
nonoxidizing chloride solutions.
Alloy 400 is low in strength in
the annealed condition. For this
reason, a variety of tempers are
used which have the effect of
increasing the strength level of
the material.
Applications:
Marine and chemical processing;
Valve, pumps,;
Heat Exchangers
Corrosion
Resistance:
Alloy 400 is more corrosion
resistant than commercially pure
nickel Monel 200 under reducing
conditions, and more resistant
than refined copper alloys under
oxidizing conditions;
Alloy 400 is resistant to most
alkalies, salts, organic
substances and atmospheric
conditions;
Alloy 400 is exceptionally
resistant to chloride stress
corrosion cracking. Application
in water, including sea and
brackish water, is a major use
of the material.
