Introduction to ERNiCrMo-4 (C-276) Welding Wire
ERNiCrMo-4 (C-276) welding wire, also known as Hastelloy C-276, is
a high-performance, nickel-based alloy renowned for its exceptional
corrosion resistance and high-temperature stability. It is widely
used in industries requiring reliable and durable welding materials
under extreme environments, such as chemical processing, oil and
gas, aerospace, and power generation.
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 and Key Properties
ERNiCrMo-4 (C-276) welding wire is designed to perform in some of
the most demanding conditions. The unique
nickel-chromium-molybdenum alloy composition provides exceptional
resistance to a variety of corrosive elements and extreme
temperatures:
Nickel (Ni) – Offers resistance to oxidation and superior corrosion
resistance, especially in reducing environments such as sulfuric
acid, hydrochloric acid, and chlorides.
Chromium (Cr) – Enhances oxidation resistance and helps retain
strength at high temperatures, ensuring durability in heat-exposed
environments like boilers and furnaces.
Molybdenum (Mo) – Provides excellent resistance to pitting, stress
corrosion cracking, and crevice corrosion, especially in
environments rich in chlorides or sulfides.
High-Temperature Strength – Retains mechanical properties at
temperatures above 1000°C, making it suitable for high-temperature
applications.
Weldability – The wire exhibits excellent weldability, providing
smooth, high-quality welds with minimal spatter and strong fusion.
Applications of ERNiCrMo-4 (C-276) Welding Wire
Due to its outstanding corrosion resistance and high-temperature
stability, ERNiCrMo-4 (C-276) welding wire is widely used in
critical industries that deal with extreme environmental
conditions. Some of the most common applications include:
✔ Chemical Processing – Ideal for reactors, heat exchangers, tanks,
and piping systems exposed to aggressive chemicals like sulfuric
acid, hydrochloric acid, phosphoric acid, and chlorides.
✔ Oil & Gas – Used extensively in offshore drilling rigs, refinery
operations, and subsea pipelines where exposure to saltwater,
hydrogen sulfide, and high-pressure systems is common.
✔ Power Generation – ERNiCrMo-4 (C-276) is essential in boilers,
heat exchangers, and nuclear power plants where high temperatures
and corrosive gases are prevalent.
✔ Aerospace & Defense – Crucial for jet engines, turbine blades,
and other high-performance components that require superior
strength and resistance to heat and corrosion under extreme
conditions.
✔ Marine & Offshore – The wire is widely used in desalination
plants, marine equipment, and offshore structures exposed to
saltwater corrosion and extreme weather conditions.
✔ Food & Pharmaceutical Industries – Perfect for sterilization
equipment, processing systems, and piping networks where hygiene
and resistance to corrosion are critical.
