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%) - This is the cornerstone of our alloy, offering unparalleled stability and performance.
Chromium (Cr): 20-23% - Elevates oxidation resistance to new heights, ensuring longevity and durability.
Cobalt (Co): 10-15% - Enhances high-temperature stability, making it indispensable for demanding applications.
Molybdenum (Mo): 8-10% - Provides formidable resistance to localized corrosion, a true asset in corrosive environments.
Iron (Fe): ≤5% - Maintains the integrity and performance of the alloy.
Our alloy excels in resisting pitting, crevice corrosion, and stress corrosion cracking (SCC) in challenging environments such as marine, chemical processing, and chloride-rich areas.
Mechanical Strength:
Exhibits high tensile strength (≥750 MPa) and remarkable creep resistance, even under prolonged high-temperature stress—ensuring reliability and endurance.
Weldability:
Seamlessly compatible with GTAW (TIG), GMAW (MIG), and SMAW processes, offering versatility and ease of use.
Minimal post-weld cracking, thanks to its low carbon content, ensuring smooth and flawless welds.
Product Forms & Specifications
Available Forms:
Welding consumables: Available as wire (0.8-4.0 mm diameter) and electrodes, catering to diverse welding needs.
Mill products: Available as round bars, sheets, plates, and coils, meeting various industry requirements.
Standards: Complies with ASTM B574, AMS 5826 (if applicable), ensuring quality and reliability in every product.
Packaging: Welding wires are sealed in moisture-proof packaging, and bulk materials come in standard crating to preserve quality.
Applications
Aerospace: Perfect for combustion chambers, turbine blades, and exhaust systems, providing unmatched performance.
Energy: Ideal for *** core components and heat exchangers, exemplifying robustness and endurance.
Oil & Gas: Essential for downhole tools, valves, and piping in sour gas environments, showcasing resilience and reliability.
Chemical Processing: Suited for reactors, scrubbers, and piping for sulfuric acid, hydrochloric acid, and seawater, ensuring excellent resistance.
Processing & Fabrication
Machining: Utilize carbide tools with low cutting speeds and ample coolant for precision and efficiency.
Heat Treatment: Perform solution annealing at 1120-1175°C followed by rapid quenching for optimal properties.
Welding Notes:
Preheat is unnecessary for thin sections, simplifying the welding process.
Post-weld heat treatment (PWHT) is optional for critical applications, offering flexibility and control.

Notes
1. Cobalt (Co) Role: Cobalt enhances high-temperature strength and reduces thermal expansion, making ERNiCrCo-4 suitable for ultra-high-temperature environments.
2. Verification Required: For ultimate assurance, confirm exact composition and certification (e.g., EN, UNS, or proprietary grades) with suppliers.
3. Alternatives: If unavailable, consider ERNiCrMo-4 (AWS A5.14 ERNiCrMo-4) or Inconel 617 (Ni-Cr-Co-Mo) as potential substitutes, offering comparable performance.
