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%), ensuring strength and resilience.
Chromium (Cr): 20-23% (enhances oxidation resistance), vital for longevity.
Cobalt (Co): 10-15% (improves high-temperature stability), perfect for demanding environments.
Molybdenum (Mo): 8-10% (resists localized corrosion), boosting durability.
Iron (Fe): ≤5%, a controlled element for balance.
Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in the most challenging acidic, alkaline, and chloride-rich environments, such as marine and chemical processing.
Mechanical Strength:
Outstanding tensile strength (≥750 MPa) paired with excellent creep resistance, ensuring reliability even under prolonged high-temperature stress.
Weldability:
Seamlessly compatible with GTAW (TIG), GMAW (MIG), and SMAW processes, ensuring versatile application.
Minimal post-weld cracking due to its low carbon content, enhances structural integrity and longevity.
Product Forms & Specifications
Available Forms:
Welding consumables: Available as wire (0.8-4.0 mm diameter) and electrodes to meet diverse needs.
Mill products: Offered in round bars, sheets, plates, and coils for various industrial applications.
Standards: Complies with ASTM B574 and AMS 5826 (if applicable) to guarantee quality and reliability.
Packaging: Welding wires are sealed in moisture-proof packaging; bulk materials are standard crated for protection.
Applications
Aerospace: Ideal for combustion chambers, turbine blades, and exhaust systems, offering unmatched performance.
Energy: Essential for *** core components and heat exchangers, providing resilience and safety.
Oil & Gas: Perfect for downhole tools, valves, and piping in sour gas environments, ensuring robustness.
Chemical Processing: Designed for reactors, scrubbers, and piping used with sulfuric acid, hydrochloric acid, and seawater, providing superior resistance.
Processing & Fabrication
Machining: Employ carbide tools with low cutting speeds and ample coolant for precision and efficiency.
Heat Treatment: Solution annealing at 1120-1175°C followed by rapid quenching for optimal performance.
Welding Notes:
Preheat is unnecessary for thin sections, simplifying procedures.
Post-weld heat treatment (PWHT) is optional for critical applications, providing flexibility.

Notes
1. Cobalt (Co) Role: Cobalt enhances high-temperature strength and reduces thermal expansion, making ERNiCrCo-4 suitable for ultra-high-temperature environments, a hallmark of quality.
2. Verification Required: Confirm exact composition and certification (e.g., EN, UNS, or proprietary grades) with suppliers to ensure authenticity and suitability.
3. Alternatives: If unavailable, ERNiCrMo-4 (AWS A5.14 ERNiCrMo-4) or Inconel 617 (Ni-Cr-Co-Mo) may serve as substitutes, maintaining excellence.
