Corrosion-Resistant ERNiCrMo-3 Welding Wire for High-Performance in Harsh Environments and Power Generation Applications

ERNiCrMo-3 is a nickel-chromium-molybdenum alloy welding wire designed for joining corrosion-resistant alloys like Inconel 625, Hastelloy, and similar high-performance materials. It offers exceptional resistance to pitting, crevice corrosion, and oxidation in harsh environments, including chemical processing, marine, and oil & gas applications. The wire delivers high tensile strength and excellent ductility, even in cryogenic conditions, making it suitable for extreme temperature services.

Key features include superior weldability with low risk of hot cracking, stable arc characteristics, and smooth bead appearance. Its composition (Ni-Cr-Mo-Nb) ensures resistance to sulfur compounds and acidic media. ERNiCrMo-3 is commonly used in GTAW (TIG) and GMAW (MIG) processes for critical components like heat exchangers, reactors, and piping systems. Proper pre-weld cleaning and controlled interpass temperatures are recommended for optimal performance.

ERNiCrMo-3 Welding Wire – Key Features

1. Superior Corrosion Resistance

• Excellent performance in highly corrosive environments, including acidic, alkaline, and chloride-rich conditions.
• Resistant to pitting, crevice corrosion, and stress corrosion cracking (SCC).

2. High-Temperature Strength & Oxidation Resistance

• Maintains mechanical integrity at elevated temperatures (up to 1200°C / 2192°F).
• Exceptional oxidation and carburization resistance in extreme thermal cycles.

3. Versatile Alloy Composition

• Nickel-chromium-molybdenum (Ni-Cr-Mo) alloy with balanced additions of iron, niobium, and tungsten.
• Conforms to AWS A5.14 (ERNiCrMo-3) and equivalent international standards (e.g., UNS N06625).

4. Excellent Weldability & Crack Resistance

• Low risk of hot cracking or porosity due to controlled impurity levels (S, P).
• Suitable for welding dissimilar metals (e.g., nickel alloys to stainless steel or carbon steel).

5. Wide Application Scope

• Ideal for:

Chemical processing equipment (reactors, pipelines).

Oil & gas (downhole tools, flue gas desulfurization systems).

Aerospace (combustion chambers, exhaust components).

Power generation (turbine blades, heat exchangers).

6. Optimized Manufacturing Quality

• Precision-drawn wire with consistent diameter and smooth surface finish.
• Minimal spatter and stable arc performance for automated/manual welding processes (TIG, MIG, SAW).

7. Compliance & Certifications

• Meets ASME, ISO, and PED requirements.
• Available with 3.1 Material Test Certificates upon request.

Technical Note: ERNiCrMo-3 is the welding filler metal counterpart to Alloy 625 (Inconel 625), ensuring matched properties in welded joints.
