ERNiCrCo-4 Product Description
Material Type: Nickel-Chromium-Cobalt-Molybdenum Superalloy
AWS Specification: AWS A5.14
Key Characteristics
1. Chemical Composition (Typical):
Nickel (Ni): The base element comprising ≥50%, forming a robust foundation for high performance.
Chromium (Cr): Comprising 20-23%, this essential element significantly enhances oxidation resistance, ensuring durability.
Cobalt (Co): With 10-15%, it improves high-temperature stability, providing exceptional strength in demanding conditions.
Molybdenum (Mo): At 8-10%, it offers superior localized corrosion resistance, safeguarding the material's integrity.
Iron (Fe): Maintained at ≤5% to ensure optimal structural performance.
Remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in harsh environments like marine, chemical processing, and more.
Mechanical Strength:
Offers high tensile strength (≥750 MPa) and exceptional creep resistance under sustained high-temperature stress.
Weldability:
Seamlessly compatible with GTAW (TIG), GMAW (MIG), and SMAW processes, ensuring versatile application.
Low carbon content minimizes post-weld cracking, enhancing weld integrity.
Product Forms & Specifications
Available Forms:
Welding consumables include wire with diameters of 0.8-4.0 mm and electrodes, catering to diverse needs.
Mill products range from round bars to sheets, plates, and coils, offering comprehensive solutions.
Standards align with ASTM B574 and AMS 5826 (as applicable), ensuring quality and consistency.
Packaging: Welding wires are sealed in moisture-proof packaging, while bulk materials receive standard crating.
Applications
Aerospace: Perfect for combustion chambers, turbine blades, and exhaust systems, providing reliable performance.
Energy: Critical for *** core components and heat exchangers, guaranteeing safety and efficiency.
Oil & Gas: Essential for downhole tools, valves, and piping in challenging sour gas environments.
Chemical Processing: Ideal for reactors, scrubbers, and piping used with sulfuric acid, hydrochloric acid, and seawater.
Processing & Fabrication
Machining: Employ carbide tools with low cutting speeds and ample coolant for precision.
Heat Treatment: Engage in solution annealing at 1120-1175°C followed by rapid quenching for optimal results.
Welding Notes:
No preheat required for thin sections, streamlining the welding process.
Post-weld heat treatment (PWHT) is optional for critical applications, adding flexibility.

Notes
1. Cobalt's Role: Enhances high-temperature strength and minimizes thermal expansion, making ERNiCrCo-4 ideal for ultra-high-temperature environments.
2. Verification Required: Confirm precise composition and certification with suppliers, such as EN, UNS, or proprietary grades.
3. Alternatives: In case of unavailability, consider ERNiCrMo-4 (AWS A5.14 ERNiCrMo-4) or Inconel 617 (Ni-Cr-Co-Mo) as viable substitutes.
