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%)
Chromium (Cr): 20-23% (enhances oxidation resistance)
Cobalt (Co): 10-15% (improves high-temperature stability)
Molybdenum (Mo): 8-10% (resists localized corrosion)
Iron (Fe): ≤5%
This material is engineered to resist pitting, crevice corrosion, and stress corrosion cracking (SCC) even in the harshest environments like acidic, alkaline, and chloride-rich conditions, perfect for marine and chemical processing industries.
Mechanical Strength:
Featuring high tensile strength (≥750 MPa), this material excels in creep resistance, efficiently handling prolonged high-temperature stress.
Weldability:
Seamlessly compatible with multiple welding processes including GTAW (TIG), GMAW (MIG), and SMAW, ensuring versatility in application.
The low carbon content significantly reduces post-weld cracking, enhancing the overall integrity of the weld.
Product Forms & Specifications
Available Forms:
Versatile welding consumables such as wire ranging from 0.8-4.0 mm diameter and electrodes.
Extensive mill products including round bars, sheets, plates, and coils cater to diverse industrial needs.
Standards: ASTM B574, AMS 5826 (if applicable).
Thoughtful packaging with sealed moisture-proof options for welding wires and standard crating for bulk materials ensures safety and integrity during transportation.
Applications
Aerospace: Ideal for high-performance components like combustion chambers, turbine blades, and exhaust systems.
Energy: Ensures reliable performance in *** core components and heat exchangers.
Oil & Gas: Perfectly suited for downhole tools, valves, and piping in challenging sour gas environments.
Chemical Processing: Durable and resistant for reactors, scrubbers, and piping handling sulfuric acid, hydrochloric acid, and seawater.
Processing & Fabrication
Machining: Employ carbide tools, maintaining low cutting speeds with ample coolant to ensure precision and longevity.
Heat Treatment: Achieve optimal results with solution annealing at 1120-1175°C followed by rapid quenching.
Welding Notes:
Thin sections do not require preheating, streamlining the welding process.
Post-weld heat treatment (PWHT) is optional for critical applications, offering flexibility in fabrication.

Notes
1. Cobalt (Co) Role: Cobalt is integral in enhancing high-temperature strength and minimizing thermal expansion, making ERNiCrCo-4 a top choice for ultra-high-temperature applications.
2. Verification Required: Always confirm the exact composition and certification, including EN, UNS, or proprietary grades, with your suppliers to ensure compliance and performance.
3. Alternatives: In the event of unavailability, consider ERNiCrMo-4 (AWS A5.14 ERNiCrMo-4) or Inconel 617 (Ni-Cr-Co-Mo) as viable substitutes, ensuring continuity in your operations.
