ERNiCrCo-4 Product Description
Material Type: Revel in the excellence of a Nickel-Chromium-Cobalt-Molybdenum Superalloy
AWS Specification: Proudly meets AWS A5.14 standards, ensuring top-tier quality
Key Characteristics
1. Chemical Composition (Typical): An impressive assemblage of elements
Nickel (Ni): The foundational element (≥50%) that offers strength and resilience
Chromium (Cr): 20-23% content that remarkably enhances oxidation resistance
Cobalt (Co): 10-15% infusion for improved stability at high temperatures
Molybdenum (Mo): 8-10% to combat localized corrosion with prowess
Iron (Fe): Kept at a minimum of ≤5% to maintain integrity
Withstands pitting, crevice corrosion, and stress corrosion cracking (SCC) in the toughest conditions like acidic, alkaline, and chloride-rich environments — ideal for marine and chemical processing.
Mechanical Strength:
Exceptional tensile strength (≥750 MPa) and unmatched creep resistance under prolonged, high-temperature stress.
Weldability:
Seamlessly compatible with GTAW (TIG), GMAW (MIG), and SMAW welding techniques.
Minimal risk of post-weld cracking thanks to its low carbon content.
Product Forms & Specifications
Available Forms: Diverse options to suit your needs
Welding consumables include wires (0.8-4.0 mm diameter) and electrodes for precision.
Mill products available in round bars, sheets, plates, and coils for versatile applications.
Standards: Compliant with ASTM B574, AMS 5826 where applicable, ensuring international reliability.
Packaging: Securely encased in sealed moisture-proof packaging for welding wires and standard crating for bulk materials.
Applications
Aerospace: Perfect for combustion chambers, turbine blades, and exhaust systems that require peak performance.
Energy: Integral in *** core components and heat exchangers, standing up to extreme conditions.
Oil & Gas: Essential for downhole tools, valves, and piping in challenging sour gas environments.
Chemical Processing: Ideal for reactors, scrubbers, and piping enduring the harshness of sulfuric acid, hydrochloric acid, and seawater.
Processing & Fabrication
Machining: Utilize carbide tools with low cutting speeds and ample coolant for optimal results.
Heat Treatment: Undergoes solution annealing at 1120-1175°C, followed by rapid quenching for superior quality.
Welding Notes:
Preheating is unnecessary for thin sections, simplifying the process.
Post-weld heat treatment (PWHT) is optional yet advisable for critical, demanding applications.

Notes
1. Cobalt (Co) Role: Enhances high-temperature strength and minimizes thermal expansion, making ERNiCrCo-4 a top choice for ultra-high-temperature environments.
2. Verification Required: Ensure exact composition and certification (e.g., EN, UNS, or proprietary grades) with suppliers to meet your specific needs.
3. Alternatives: Should availability be an issue, ERNiCrMo-4 (AWS A5.14 ERNiCrMo-4) or Inconel 617 (Ni-Cr-Co-Mo) can be reliable substitutes.
