ERNiCrCo-4 Product Description
Material Type: A premium Nickel-Chromium-Cobalt-Molybdenum Superalloy, designed to meet the highest standards of durability and performance.
AWS Specification: Complies with AWS A5.14 to ensure top-notch quality and reliability for demanding applications.
Key Characteristics
1. Chemical Composition (Typical):
Nickel (Ni): Serves as the base element, constituting no less than 50% to provide exceptional corrosion resistance.
Chromium (Cr): Ranges between 20-23%, significantly boosting oxidation resistance for longevity and durability.
Cobalt (Co): Comprising 10-15%, this element enhances high-temperature stability essential for critical environments.
Molybdenum (Mo): Present in 8-10% to effectively resist localized corrosion, ensuring longevity in challenging conditions.
Iron (Fe): Kept at minimal levels (≤5%) to maintain the integrity and performance of the alloy.
Engineered for superior resistance against pitting, crevice corrosion, and stress corrosion cracking (SCC) even in aggressive acidic, alkaline, and chloride-rich settings such as marine and chemical processing environments.
Mechanical Strength:
Provides high tensile strength (≥750 MPa) and exceptional creep resistance, maintaining integrity under prolonged high-temperature stress.
Weldability:
This versatile alloy is compatible with GTAW (TIG), GMAW (MIG), and SMAW welding processes, ensuring adaptability across various projects.
Features minimal post-weld cracking, attributed to its low carbon content, facilitating smooth and durable welds.
Product Forms & Specifications
Available Forms:
Offered as welding consumables, including wire (0.8-4.0 mm diameter) and electrodes, to meet diverse project needs.
Also available as mill products like round bars, sheets, plates, and coils, providing versatility in application.
Meets standards such as ASTM B574 and AMS 5826 (if applicable) to guarantee compliance and quality assurance.
Secure packaging includes sealed moisture-proof packs for welding wires and standard crating for bulk materials, preserving product integrity during transportation.
Applications
Aerospace: Perfect for components exposed to extreme conditions such as combustion chambers, turbine blades, and exhaust systems.
Energy: Ideal for *** core components and heat exchangers, where maximum reliability is crucial.
Oil & Gas: Suitable for manufacturing downhole tools, valves, and piping, particularly in sour gas environments.
Chemical Processing: Utilized in reactors, scrubbers, and piping systems for sulfuric acid, hydrochloric acid, and seawater applications.
Processing & Fabrication
Machining: Employ carbide tools with reduced cutting speeds and ensure the use of ample coolant for optimal results.
Heat Treatment: Requires solution annealing at 1120-1175°C followed by rapid quenching, guaranteeing optimal material properties.
Welding Notes:
No preheat necessary for thin sections, simplifying preparation and reducing time and cost.
Post-weld heat treatment (PWHT) is optional but recommended for critical applications to enhance durability and performance.
