Nickel alloy valves are used extensively in applications
where heat resistance and/or corrosion resistance is required. Nickel
Alloy valves in this class are designed to resist failure from both
of these mechanisms. Nickel alloy valves are not suitable for high
temperature sulphur rich environments.This nickel alloy valves are
frequently sold under trade name specifications but most are listed
in the Unified Numbering System. Common trade names are HASTELLOY,
INCOLOY, INCONEL, NICROFER, NICROM and NIMONIC.
Nickel alloys valves have higher strength and longer life at elevated
temperature than most alloys. The designer however, must determine
the expected life of each component and use the appropriate creep
and rupture strength in the design before selecting valves.
Nickel Alloy Valves are used in
many applications where they are subjected to harsh environments at
high temperatures. Nickel alloys valves offer excellent corrosion
resistance to a wide range of corrosive media. However, as with all
types of corrosion, many factors influence the rate of attack. Nickel
alloy valves found to have a profound effect on the thermal expansion
of iron.

Some high-temperature variants include:
Nickel Alloy 601 valves - Lower nickel (61%) content with aluminum
and silicon additions for improved oxidation and nitriding resistance.
Nickel Alloy X750 valves - Aluminum and titanium additions for
age hardening
Nickel Alloy 718 valves -Titanium and niobium additions to overcome
strainage cracking problems during welding and weld repair
Nickel Alloy X (48Ni-22Cr-18Fe-9Mo + W) valves -High-temperature
flat-rolled product for aerospace applications
Nickel Waspaloy (60Ni-19Cr-4Mo-3Ti-1.3Al) valves - Proprietary
alloy for jet engine applications
Some corrosion-resistant variants in the Ni-Cr-Fe system include.
Nickel Alloy 625 valves - The addition of 9% Mo plus 3% Nb offers
both high-temperature and wet corrosion resistance; resists pitting
and crevice corrosion.
Nickel Alloy G3/G30 (Ni-22Cr-19Fe-7Mo-2Cu) valves -The increased
molybdenum content in these alloys offers improved pitting and crevice
corrosion resistance.
Nickel Alloy C-22 (Ni-22Cr-6Fe-14Mo-4W) valves -Superior corrosion
resistance in oxidizing acid chlorides, wet chlorine, and other
severe corrosive environments.
Nickel Alloy C-276 (17% Mo plus 3.7W) valves -Good seawater corrosion
resistance and excellent pitting and crevice corrosion resistance.
Nickel Alloy 690 (27% Cr addition) valves -Excellent
oxidation and nitric acid resistance; specified for nuclear waste
disposal by the vitreous encapsulation method.Iron-Nickel-Chromium
Alloys Valves. This series of alloy Valves has also found extensive
use in the high-temperature petrochemical environments, where
sulfur-containing feedstocks (naphtha and heavy oils) are cracked
into component distillate parts. Not only were these valves resistant
to chloride-ion stress-corrosion cracking, but they also offered
resistance to polythionic acid cracking. Some alloys of commercial
importance include:
Nickel Alloy 800 (Fe-32Ni-21Cr) valves -The basic alloy in the
Fe-Ni-Cr system; resistant to oxidation and carburization at elevated
temperatures.
Nickel Alloy 800HT valves -Similar to 800H with further modification
to combined titanium and aluminum levels (0.85 to 1.2%) to ensure
optimum high-temperature properties.
Nickel Alloy 801 valves -Increased titanium content (0.75 to 1.5%);
exceptional resistance to polythionic acid cracking.
Nickel Alloy 802 valves -High-carbon version (0.2 to 0.5%) for
improved strength at high temperatures.
Nickel Alloy 825 (Fe-42Ni-21.5Cr-2Cu) valves -Stabilized with
titanium addition (0.6 to 1.2%). Also contains molybdenum (3%) for
pitting resistance in aqueous corrosion applications. Copper content
bestows resistance to sulfuric acid.
Nickel Alloy 925 valves -Addition of titanium and aluminum to
825 composition for strengthening through age hardening.
