ERNiCrMo-10 Super Alloy Nickel Welding Wire with Good Weldability and High-Temperature Strength
ERNiCrMo-10 is a nickel-based alloy welding wire designed for high-performance applications in corrosive and high-temperature environments. With excellent resistance to oxidation, carburization, and sulfidation, it is widely used in chemical processing, power generation, and oil & gas industries. The wire exhibits superior weldability and mechanical properties, including high tensile strength and creep resistance, making it ideal for joining dissimilar metals and repairing nickel-chromium-molybdenum alloys. Its low carbon content minimizes carbide precipitation, ensuring optimal corrosion resistance in welded joints. ERNiCrMo-10 is compliant with AWS A5.14/ASME SFA-5.14 standards, guaranteeing consistent quality. Suitable for TIG, MIG, and SAW processes, it delivers crack-free, durable welds even under extreme conditions, enhancing equipment longevity and operational reliability.

- Low risk of carbide precipitation or sigma phase formation in prolonged service.
3. Optimized Alloy Composition
- Ni-Cr-Mo alloy system (UNS N06022) with balanced additions of:
- Nickel (Ni): Ensures ductility and thermal stability.
- Chromium (Cr): Enhances oxidation resistance.
- Molybdenum (Mo): Improves localized corrosion resistance.
- Low carbon content (<0.015%) to minimize intergranular corrosion.
4. Excellent Weldability
- Low susceptibility to hot cracking or porosity.
- Suitable for GTAW (TIG), GMAW (MIG), SAW, and other welding processes.
- Smooth arc transfer and minimal spatter for high-quality weld deposits.
5. Versatile Applications
- Ideal for welding and overlay of:
- Chemical processing equipment (reactors, piping).
- Oil & gas components (downhole tools, flue gas scrubbers).
- Power generation systems (FGD units, boiler parts).
- Compatible with base metals like Inconel 625, Hastelloy C-22, and similar alloys.
6. Certifications & Compliance
- Conforms to AWS A5.14/ASME SFA-5.14 (ERNiCrMo-10 classification).
- Certified for ASME BPVC, PED 2014/68/EU, and NACE MR0175 standards.
Technical Advantages Over Competitors
