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)
Cobalt (Co): 10-15% (improves high-temperature stability)
Molybdenum (Mo): 8-10% (resists localized corrosion)
Iron (Fe): ≤5%
This superalloy excels in corrosive environments, particularly in marine and chemical processing, by resisting pitting, crevice corrosion, and stress corrosion cracking (SCC) even when exposed to harsh acidic, alkaline, and chloride-rich conditions.
Mechanical Strength:
Engineered for strength, it boasts high tensile strength (≥750 MPa) and exceptional creep resistance, enduring prolonged high-temperature stress with grace.
Weldability:
Easily adaptable to various welding methods, including GTAW (TIG), GMAW (MIG), and SMAW processes, ensuring versatility in application.
Its low carbon content ensures minimal post-weld cracking, enhancing the integrity and longevity of your welds.
Product Forms & Specifications
Available Forms:
Our portfolio includes premium welding consumables such as wire (0.8-4.0 mm diameter) and electrodes.
Mill products: Available in versatile forms like round bars, sheets, plates, and coils to meet diverse project needs.
Standards: Fully compliant with ASTM B574, AMS 5826 standards (where applicable).
Packaging: To maintain quality, welding wires are sealed in moisture-proof packaging, while bulk materials are secured in standard crating.
Applications
Aerospace: Ideal for critical components such as combustion chambers, turbine blades, and exhaust systems, ensuring reliability and performance.
Energy: Essential for *** core components and heat exchangers, contributing to the industry's high safety standards.
Oil & Gas: Perfect for downhole tools, valves, and piping, especially in challenging sour gas environments.
Chemical Processing: Suited for reactors, scrubbers, and piping systems handling sulfuric acid, hydrochloric acid, and seawater effectively.
Processing & Fabrication
Machining: Achieve precision with carbide tools at low cutting speeds, supplemented by ample coolant.
Heat Treatment: Optimize properties with solution annealing at 1120-1175°C, followed by rapid quenching.
Welding Notes:
No preheating required for thin sections, offering efficiency in fabrication.
Post-weld heat treatment (PWHT) is available for critical applications, enhancing durability.

Notes
1. Cobalt (Co) Role: The addition of cobalt not only boosts high-temperature strength but also reduces thermal expansion, making ERNiCrCo-4 highly suitable for ultra-high-temperature environments.
2. Verification Required: Always confirm the precise composition and certification (e.g., EN, UNS, or proprietary grades) with trusted suppliers for quality assurance.
3. Alternatives: If unavailable, consider substitutes like ERNiCrMo-4 (AWS A5.14 ERNiCrMo-4) or Inconel 617 (Ni-Cr-Co-Mo) for similar performance qualities.
