ERNiCrCo-4: A Masterpiece of Engineering Excellence
Material Type: Experience the unparalleled durability and adaptability of Nickel-Chromium-Cobalt-Molybdenum Superalloy.
AWS Specification: Strictly adheres to AWS A5.14 standards, ensuring premium quality and consistency.
Key Characteristics: Unmatched performance and reliability in challenging environments.
1. Chemical Composition (Typical): Crafted for optimal performance and resilience.
Nickel (Ni): The primary constituent (≥50%) offers exceptional strength and resilience.
Chromium (Cr): 20-23% inclusion bolsters oxidation resistance, ensuring long-lasting protection.
Cobalt (Co): Present at 10-15% to enhance stability at elevated temperatures.
Molybdenum (Mo): 8-10% content provides robust resistance to localized corrosion.
Iron (Fe): Limited to ≤5% for optimal alloy integrity.
Remarkable resistance to pitting, crevice corrosion, and SCC in hostile acidic, alkaline, and chloride-rich conditions, perfect for marine and chemical sectors.
Mechanical Strength: Built to endure and excel under stress.
Boasting a high tensile strength of ≥750 MPa, coupled with superior creep resistance under continuous high-temperature exposure.
Weldability: Versatile and efficient for a range of welding techniques.
Seamlessly compatible with GTAW (TIG), GMAW (MIG), and SMAW processes, ensuring minimal hassle.
Engineered for minimal post-weld cracking, thanks to its low carbon content.
Product Forms & Specifications: Diverse and adaptable to meet your every need.
Available Forms: Tailored to suit diverse industrial applications.
Welding consumables: Choose from wires (0.8-4.0 mm diameter) and electrodes for precise applications.
Mill products: Available in round bars, sheets, plates, and coils for versatile utility.
Conforms to ASTM B574 and AMS 5826 standards (where applicable) for assured quality.
Packaging: Welding wires are sealed in moisture-proof packages, while bulk materials come in standard crates.
Applications: Perfectly suited for high-stakes sectors where performance is non-negotiable.
Aerospace: Ideal for high-performance parts like combustion chambers, turbine blades, and exhaust systems.
Energy: Essential for *** core components and efficient heat exchangers.
Oil & Gas: Reliable in demanding sour gas environments for downhole tools, valves, and piping.
Chemical Processing: Suited for reactors, scrubbers, and piping handling aggressive substances like sulfuric and hydrochloric acids, and seawater.
Processing & Fabrication: Precision-engineered for exacting manufacturing processes.
Machining: Employ carbide tools at low cutting speeds with generous coolant for optimal results.
Heat Treatment: Requires solution annealing between 1120-1175°C followed by rapid quenching to ensure performance.
Welding Notes: Guidance for achieving superior welds.
No preheat required for thin sections, simplifying the welding process.
Post-weld heat treatment (PWHT) is recommended for critical applications to enhance weld quality.

Notes: Additional insights for making informed decisions.
1. Cobalt (Co) Role: Enhances high-temperature strength and reduces thermal expansion, making ERNiCrCo-4 perfect for ultra-high-temperature environments.
2. Verification Required: Confirm precise composition and certification (e.g., EN, UNS, or proprietary grades) with suppliers for assurance.
3. Alternatives: If unavailable, consider ERNiCrMo-4 (AWS A5.14 ERNiCrMo-4) or Inconel 617 (Ni-Cr-Co-Mo) as reliable substitutes.
