ERNiCrCo-4 Product Description: Unveiling Excellence
Material Type: Premium Nickel-Chromium-Cobalt-Molybdenum Superalloy
AWS Specification: Compliant with AWS A5.14
Key Characteristics: Distinguished Features
1. Chemical Composition (Typical): Unparalleled Quality
Nickel (Ni): Base element (≥50%). The backbone of strength and resilience.
Chromium (Cr): 20-23% (enhancing oxidation resistance to new heights).
Cobalt (Co): 10-15% (improving high-temperature stability remarkably).
Molybdenum (Mo): 8-10% (offering exceptional resistance to localized corrosion).
Iron (Fe): ≤5% - maintaining structural integrity.
Outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in hostile environments such as acidic, alkaline, and chloride-rich settings (e.g., marine, chemical processing).
Mechanical Strength: Exceptional Durability
High tensile strength (≥750 MPa) and unmatched creep resistance under prolonged high-temperature stress.
Weldability: Seamless Integration
Compatible with various welding processes: GTAW (TIG), GMAW (MIG), and SMAW.
Minimal post-weld cracking thanks to a low carbon content, ensuring smoother operations.
Product Forms & Specifications: Versatile Options
Available Forms: Tailored to Your Needs
Welding consumables: Wide range of wire (0.8-4.0 mm diameter) and electrodes available.
Mill products: Available in round bars, sheets, plates, and coils for diverse applications.
Standards: Complies with ASTM B574, AMS 5826 (if applicable), ensuring quality you can trust.
Packaging: Robust and Secure
Applications: Wide-Ranging Impact
Aerospace: Perfect for combustion chambers, turbine blades, and exhaust systems.
Energy: Ideal for *** core components and heat exchangers.
Oil & Gas: Engineered for downhole tools, valves, and piping in sour gas environments.
Chemical Processing: Reliable for reactors, scrubbers, and piping for sulfuric acid, hydrochloric acid, and seawater applications.
Processing & Fabrication: Precision Craftsmanship
Machining: Utilize carbide tools with low cutting speeds and ample coolant for pristine results.
Heat Treatment: Solution annealing at 1120-1175°C followed by rapid quenching for optimal properties.
Welding Notes: Expert Guidance
Preheat is unnecessary for thin sections, simplifying the process.
Post-weld heat treatment (PWHT) is optional, reserved for critical applications.

Notes: Essential Insights
1. Cobalt (Co) Role: Enhances high-temperature strength and reduces thermal expansion, securing ERNiCrCo-4's suitability for ultra-high-temperature environments.
2. Verification Required: Ensure exact composition and certification (e.g., EN, UNS, or proprietary grades) with trusted suppliers.
3. Alternatives: If unavailable, consider ERNiCrMo-4 (AWS A5.14 ERNiCrMo-4) or Inconel 617 (Ni-Cr-Co-Mo) as excellent substitutes.
