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%) - The foundation of our alloy's robust structure.
Chromium (Cr): 20-23% - Augments resistance to oxidation, ensuring longevity.
Cobalt (Co): 10-15% - Enhances stability at elevated temperatures, perfecting performance.
Molybdenum (Mo): 8-10% - Offers superior defense against localized corrosion.
Iron (Fe): ≤5% - Balances the composite for enhanced durability.
Our superalloy excels by resisting pitting, crevice corrosion, and stress corrosion cracking (SCC) in environments rich in acid, alkali, and chlorides, such as marine and chemical processing settings.
Mechanical Strength:
Boasts high tensile strength (≥750 MPa) and impressive creep resistance, even under sustained high-temperature stress.
Weldability:
Perfectly compatible with diverse welding processes: GTAW (TIG), GMAW (MIG), and SMAW.
Its low carbon content significantly reduces the chances of post-weld cracking.
Product Forms & Specifications
Available Forms:
Welding consumables: Available in wire forms (0.8-4.0 mm diameter) and electrodes, catering to varied industrial needs.
Mill products: Offered as round bars, sheets, plates, and coils, ensuring versatility.
Standards: Compliant with ASTM B574, AMS 5826 (where applicable).
Packaging: Welding wires are encased in sealed, moisture-proof packaging; bulk materials are standard crated for your convenience.
Applications
Aerospace: Ideal for combustion chambers, turbine blades, and exhaust systems.
Energy: Vital for *** core components and heat exchangers.
Oil & Gas: Perfect for downhole tools, valves, and piping in sour gas conditions.
Chemical Processing: Essential for reactors, scrubbers, and piping in sulfuric acid, hydrochloric acid, and seawater environments.
Processing & Fabrication
Machining: Employ carbide tools at low cutting speeds, ensuring generous coolant application.
Heat Treatment: Conduct solution annealing at 1120-1175°C followed by rapid quenching for optimal results.
Welding Notes:
Preheat is not necessary for thin sections, simplifying the process.
Post-weld heat treatment (PWHT) is optional for critical applications, tailoring to specific needs.

Notes
1. Cobalt (Co) Role: Cobalt significantly enhances high-temperature strength and minimizes thermal expansion, rendering ERNiCrCo-4 perfect for ultra-high-temperature environments.
2. Verification Required: Confirm exact composition and ensure certification (e.g., EN, UNS, or proprietary grades) with suppliers.
3. Alternatives: Should availability be an issue, ERNiCrMo-4 (AWS A5.14 ERNiCrMo-4) or Inconel 617 (Ni-Cr-Co-Mo) may serve as reliable substitutes.
