Product Description

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.Nicrmo TIG Welding Wire: Superior Quality for Aerospace ApplicationsNicrmo TIG Welding Wire: Superior Quality for Aerospace ApplicationsNicrmo TIG Welding Wire: Superior Quality for Aerospace ApplicationsNicrmo TIG Welding Wire: Superior Quality for Aerospace ApplicationsNicrmo TIG Welding Wire: Superior Quality for Aerospace ApplicationsNicrmo TIG Welding Wire: Superior Quality for Aerospace ApplicationsNicrmo TIG Welding Wire: Superior Quality for Aerospace Applications
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.
