Product Description ERNiCrCo-4 Product DescriptionMaterial Type: Nickel-Chromium-Cobalt-Molybdenum SuperalloyAWS Specification: AWS A5.14Key Characteristics1. 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 & SpecificationsAvailable 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.ApplicationsAerospace: 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 & FabricationMachining: 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.________________________________________Notes1. 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.AWS A5.4ERNi-1ERNiCu-7ERNiCr-3ERNiCrFe-5ERNiCrMo-3ERNiCrMo-4ERNiCrMo-7TS(N/mm2)460541671560790729780EL(%)30393930433335C0.020.020.030.030.00370.0020.05Mn0.31.73.0510.030.120.6Si0.160.440.370.040.0290.070.02P0.00120.007/0.0040.0030.0030.003Ti2.3/0.01/0.088//S0.0050.008/0.0020.0010.0015 Cr//19.8615.721.9515.916.7Ni96.565.6872.875.0664.65REMREMCu/REM0.060.030.0090.008/Mo///0.039.0415.915.8Nb//2.42.33.61//V/////0.01/Fe/0.70.237.90.194.122.2
