Introduction to ERNiCrMo-4 (C-276) Welding Wire
ERNiCrMo-4 (commonly known as Hastelloy C-276 welding wire) is a
high-performance nickel-chromium-molybdenum alloy designed for
extreme corrosion resistance and durability. This welding wire is
widely used in chemical processing, power generation, marine, and
aerospace industries where materials are exposed to harsh
environments, high temperatures, and aggressive chemical
conditions.
As a direct factory supplier, we offer bulk order discounts and
wholesale pricing, ensuring that industrial buyers receive
high-quality welding wire at the best possible price.
ERNiCrMo-3 is used primarily for gas tungsten and gas metal arc and matching
composition base metals.It is also used for welding Inconel 601 and
Incoloy 800. It can be used to weld dissimilar metal combinations
such as steel, stainless steel, Inconel and Incoloy alloys.
ERNiCrMo-4 is used for welding nickel-chromium-molybdenum base materials to
itself, steel and other nickel base alloys and for cladding steel.
ERNiCrMo-10 is used for welding nickel-chromium-molybdenum base materials to
themselves, steel and other nickel base alloys, and for cladding
steels. Can be used to weld duplex, super duplex stainless steels.
ERNiCrMo-14 is used for gas-tungsten-arc and gas-metal-arc welding of duplex,
super-duplex and super-austenitic stainless steels, as well as
nickel alloys such as UNS N06059 and N06022, INCONEL alloy C-276,
and INCONEL alloys 22, 625, and 686.
ERNiCrFe-7 is used for gas-tungsten-arc and gas-metal-arc welding of INCONEL
690.
ENiCrFe-3 electrodes are used for welding of nickel-chromium-iron alloys to
themselves and for dissimilar welding between nickel-chromium-iron
alloys and steels or stainless steels.
ERCuNi is used for gas metal and gas tungsten arc welding. Can also be
used by oxy-fuel welding of 70/30, 80/20, and 90/10 copper nickel
alloys. A barrier layer of nickel alloy 610 is recommended prior to
overlaying steel with GMAW weld process.
ERNiCu-7 is a copper-nickel alloy base wire for GMAW and GTAW welding of
Monel alloys 400 and 404. Also used for overlaying steel after
first applying Layer of 610 nickel
ERNi-1 is used for GMAW, GTAW and ASAW welding of Nickel 200 and 201,
joining these alloys to stainless and carbon steels, and other
nickel and copper-nickel base metals. Also used for overlaying
steel.
Material Composition & Properties
ERNiCrMo-4 (C-276) is formulated with a specialized combination of
nickel, chromium, molybdenum, tungsten, and iron, which provides
exceptional corrosion resistance and high mechanical strength:
Nickel (Ni) ~57% – Ensures strong corrosion resistance,
particularly in acidic and oxidizing environments.
Chromium (Cr) 14.5-16.5% – Enhances oxidation resistance, making it
suitable for high-temperature applications.
Molybdenum (Mo) 15-17% – Provides superior resistance to pitting
and crevice corrosion, essential for marine and chemical
industries.
Tungsten (W) 3-4.5% – Improves high-temperature stability and
strength.
Iron (Fe) ≤5% – Contributes to structural integrity while
maintaining corrosion resistance.
Key Features of ERNiCrMo-4 (C-276) Welding Wire
