ERNiCrCo-4 Product Description
Material Type: Dive into the realm of advanced materials with our Nickel-Chromium-Cobalt-Molybdenum Superalloy, a hallmark of innovation and durability.
AWS Specification: Compliant with AWS A5.14, ensuring reliability and performance under demanding conditions.
Key Characteristics
1. Chemical Composition (Typical): Discover the robust composition that fortifies our product's excellence.
Nickel (Ni): As the foundational element, Nickel constitutes ≥50%, ensuring strength and resilience.
Chromium (Cr): Present at 20-23%, Chromium enhances the product's oxidation resistance, crucial for longevity in harsh environments.
Cobalt (Co): With a concentration of 10-15%, Cobalt significantly boosts high-temperature stability, making it indispensable for rigorous applications.
Molybdenum (Mo): At 8-10%, Molybdenum is key in resisting localized corrosion, safeguarding the product's integrity.
Iron (Fe): Limited to ≤5%, maintaining the superior quality of the alloy.
This superalloy is engineered to combat pitting, crevice corrosion, and stress corrosion cracking (SCC) even in the most challenging acidic, alkaline, and chloride-rich environments, including marine and chemical processing settings.
Mechanical Strength:
Built to last with high tensile strength (≥750 MPa) and exceptional creep resistance, performing admirably under prolonged high-temperature stress.
Weldability:
Exemplary compatibility with GTAW (TIG), GMAW (MIG), and SMAW processes, ensuring easy and effective weldability.
Minimal post-weld cracking is achieved thanks to the low carbon content, assuring you of a smoother finish and greater product reliability.
Product Forms & Specifications
Available Forms:
Versatile welding consumables available in wire forms (0.8-4.0 mm diameter) and electrodes to suit various applications.
Mill products offered include round bars, sheets, plates, and coils, catering to diverse industrial needs.
Adheres to Standards: Meets ASTM B574, AMS 5826 (where applicable), ensuring consistency and quality.
Secure and protected packaging: Our welding wires come in sealed moisture-proof packaging, while standard crating is provided for bulk materials.
Applications
Aerospace: Perfect for manufacturing combustion chambers, turbine blades, and exhaust systems, where performance is critical.
Energy: Ideal for *** core components and heat exchangers, underpinning safety and efficiency.
Oil & Gas: Designed for downhole tools, valves, and piping in sour gas environments, delivering reliability when it matters most.
Chemical Processing: Suited for reactors, scrubbers, and piping handling aggressive substances like sulfuric acid, hydrochloric acid, and seawater.
Processing & Fabrication
Machining: Utilize carbide tools with low cutting speeds and ample coolant to achieve precision and efficiency.
Heat Treatment: Engage in solution annealing at 1120-1175°C followed by rapid quenching for optimal results.
Welding Notes:
Preheat is unnecessary for thin sections, simplifying the welding process.
Post-weld heat treatment (PWHT) is optional, yet recommended for critical applications to enhance performance.

Notes
1. Cobalt (Co) Role: Cobalt's presence boosts high-temperature strength and curtails thermal expansion, rendering ERNiCrCo-4 highly suitable for ultra-high-temperature environments.
2. Verification Required: Always confirm the exact composition and certification such as EN, UNS, or proprietary grades with suppliers for assurance.
3. Alternatives: Should this be unavailable, consider ERNiCrMo-4 (AWS A5.14 ERNiCrMo-4) or Inconel 617 (Ni-Cr-Co-Mo) as potential substitutes.
