Product Description

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.
