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.

ERNiCrMo-10 Special Welding Wires – Key Features

1. Superior Corrosion Resistance

• Exceptional performance in highly corrosive environments, including:
• Sulfuric, phosphoric, and hydrochloric acid media
• Chloride-induced stress corrosion cracking (SCC) conditions
• Resistant to pitting and crevice corrosion in oxidizing/reducing atmospheres.

2. High-Temperature Stability

• Maintains mechanical integrity at elevated temperatures (up to 1,000°C/1,832°F).
• 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

• Consistent bead appearance: Uniform weld metal chemistry with minimal dilution effects.
• Post-weld heat treatment (PWHT) optional: Retains properties even without PWHT.
• Available forms: Spooled wires (0.8–2.4 mm), straight lengths, or custom coils.
