Introduction to ERNiCrMo-4 (C-276) Welding Wire
ERNiCrMo-4, also known as Hastelloy C-276, is a high-performance nickel-based welding wire designed for superior corrosion resistance, high-temperature strength, and excellent weldability. This alloy is widely used in offshore structures, chemical processing plants, and other demanding industrial environments that require protection against acidic, chloride-rich, and high-pressure conditions.

With factory-direct wholesale pricing, we provide top-quality ERNiCrMo-4 (C-276) welding wire at the best value. Our products ensure strong, durable, and corrosion-resistant welds, making them the preferred choice for critical applications in extreme environments.

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 engineered to withstand the harshest conditions. Its nickel-chromium-molybdenum composition provides outstanding corrosion resistance and mechanical strength:

Nickel (Ni) (≈ 57%) – Ensures exceptional resistance to oxidation, corrosion, and stress cracking, especially in marine and chemical environments.
Chromium (Cr) (≈ 15-16.5%) – Enhances oxidation resistance and helps retain structural integrity in high-temperature applications.
Molybdenum (Mo) (≈ 15-17%) – Provides superior protection against pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-rich environments.
Iron (Fe) (≤ 5%) – Optimized for improved mechanical strength while maintaining corrosion resistance.
Tungsten (W) (≈ 3-4.5%) – Enhances high-temperature stability and overall corrosion resistance.

Key Features of ERNiCrMo-4 (C-276) Welding Wire
✔ Exceptional Corrosion Resistance – Outstanding performance in acidic, chloride-rich, and oxidizing environments, preventing material degradation over time.
✔ High-Temperature Strength – Retains mechanical properties even in temperatures exceeding 1000°C, making it ideal for extreme applications.
✔ Superior Weldability – Produces smooth, crack-free welds with minimal porosity and excellent fusion to base metals.
✔ Resistant to Stress Corrosion Cracking (SCC) – Suitable for offshore oil platforms, pipelines, and marine applications, where long-term durability is critical.
✔ Excellent Compatibility – Compatible with dissimilar metal welding, making it versatile for joining different materials.
