ERNiCrCo-4 Product Description
Material Type: Nickel-Chromium-Cobalt-Molybdenum Superalloy
AWS Specification: AWS A5.14
Key Characteristics
1. Chemical Composition (Typical):
Nickel (Ni): Base element (≥50%)
Chromium (Cr): 20-23% - Enhances oxidation resistance, ensuring longevity and durability in harsh environments.
Cobalt (Co): 10-15% - Boosts high-temperature stability, ideal for demanding applications.
Molybdenum (Mo): 8-10% - Provides excellent resistance against localized corrosion.
Iron (Fe): ≤5%
Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in acidic, alkaline, and chloride-rich environments such as marine and chemical processing scenarios.
Mechanical Strength:
Remarkable high tensile strength (≥750 MPa) and superior creep resistance under extended high-temperature stresses.
Weldability:
Compatible with GTAW (TIG), GMAW (MIG), and SMAW processes, offering versatile welding options.
Minimal post-weld cracking due to its low carbon content, ensuring seamless and durable welds.
Product Forms & Specifications
Available Forms:
Welding consumables: Available as wire in diameters from 0.8 mm to 4.0 mm, as well as electrodes for varied applications.
Mill products include round bars, sheets, plates, and coils to suit diverse project needs.
Standards: Conforms to ASTM B574, AMS 5826 specifications, ensuring premium quality.
Packaging: Comes in sealed moisture-proof packaging for welding wires and standard crating for bulk materials to maintain integrity.
Applications
Aerospace: Essential for combustion chambers, turbine blades, and exhaust systems, contributing to performance and safety.
Energy: Ideal for *** core components and heat exchangers, enhancing efficiency and reliability.
Oil & Gas: Perfect for downhole tools, valves, and piping in harsh sour gas environments.
Chemical Processing: Suited for reactors, scrubbers, and piping handling sulfuric acid, hydrochloric acid, and seawater.
Processing & Fabrication
Machining: Achieve optimal results using carbide tools at low cutting speeds with ample coolant provision.
Heat Treatment: Involves solution annealing at temperatures between 1120-1175°C, followed by rapid quenching for enhanced material properties.
Welding Notes:
Preheat is not necessary for thin sections, promoting efficiency.
Post-weld heat treatment (PWHT) is optional for critical applications, allowing flexibility.

Notes
1. Cobalt (Co) Role: By enhancing high-temperature strength and reducing thermal expansion, Cobalt ensures ERNiCrCo-4's suitability for ultra-high-temperature environments.
2. Verification Required: Always confirm exact composition and certification (e.g., EN, UNS, or proprietary grades) with suppliers for assured quality.
3. Alternatives: Should this product be unavailable, ERNiCrMo-4 (AWS A5.14 ERNiCrMo-4) or the versatile Inconel 617 (Ni-Cr-Co-Mo) can serve as excellent substitutes.
