Nickel Alloy Forged Bars are used extensively in applications
where heat resistance and/or corrosion resistance is required. Nickel Alloy Forged Bars Manufacturers and Suppliers in this class are designed to resist failure from
both of these mechanisms. Nickel Alloy Forged Bars
are not suitable for high temperature sulphur rich environments.This
nickel alloy Forged bars 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 Forged bars 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
Forged bars.
Nickel alloy Forged bars are used
in many applications where they are subjected to harsh environments
at high temperatures. Nickel alloys Forged bars 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 Forged bars found to have a profound effect on the thermal expansion
of iron.
Some high-temperature variants include:
Nickel Alloy 601 Forged bars - Lower nickel (61%) content with aluminum
and silicon additions for improved oxidation and nitriding resistance.
Nickel Alloy X750 Forged bars - Aluminum and titanium additions for
age hardening
Nickel Alloy 718 Forged bars -Titanium and niobium additions to overcome
strainage cracking problems during welding and weld repair
Nickel Alloy X (48Ni-22Cr-18Fe-9Mo + W) Forged bars -High-temperature
flat-rolled product for aerospace applications
Nickel Waspaloy (60Ni-19Cr-4Mo-3Ti-1.3Al) Forged bars - Proprietary
alloy for jet engine applications
Some corrosion-resistant variants in the Ni-Cr-Fe system include.
Nickel Alloy 625 Forged bars - 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) Forged bars -The increased
molybdenum content in these alloys offers improved pitting and crevice
corrosion resistance.
Nickel Alloy C-22 (Ni-22Cr-6Fe-14Mo-4W) Forged bars -Superior corrosion
resistance in oxidizing acid chlorides, wet chlorine, and other
severe corrosive environments.
Nickel Alloy C-276 (17% Mo plus 3.7W) Forged bars -Good seawater corrosion
resistance and excellent pitting and crevice corrosion resistance.
Nickel Alloy 690 (27% Cr addition) Forged bars -Excellent
oxidation and nitric acid resistance; specified for nuclear waste
disposal by the vitreous encapsulation method.
Iron-Nickel-Chromium Alloys Forged bars. This series of alloy Forged bars
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 Forged bars 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) Forged bars -The basic alloy in the
Fe-Ni-Cr system; resistant to oxidation and carburization at elevated
temperatures.
Nickel Alloy 800HT Forged bars -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 Forged bars -Increased titanium content (0.75 to 1.5%);
exceptional resistance to polythionic acid cracking.
Nickel Alloy 802 Forged bars -High-carbon version (0.2 to 0.5%) for
improved strength at high temperatures.
Nickel Alloy 825 (Fe-42Ni-21.5Cr-2Cu) Forged bars -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 Forged bars -Addition of titanium and aluminum to
825 composition for strengthening through age hardening.
