ERNiCrCo-4 Product Description
Material Type: Introducing the Nickel-Chromium-Cobalt-Molybdenum Superalloy, a masterpiece of advanced metallurgy, engineered to meet the rigorous demands of modern industry.
AWS Specification: Our ERNiCrCo-4 proudly adheres to the esteemed AWS A5.14 standards, ensuring top-notch quality and reliability.
Key Characteristics
1. Chemical Composition (Typical): Dive into the robust and precise chemical composition that sets our product apart.
Nickel (Ni): The cornerstone of our alloy, Nickel boasts a base element presence of ≥50%, offering unmatched strength and durability.
Chromium (Cr): Present at 20-23%, Chromium significantly boosts oxidation resistance, essential for longevity.
Cobalt (Co): With a composition of 10-15%, Cobalt ensures high-temperature stability, perfect for demanding environments.
Molybdenum (Mo): At 8-10%, Molybdenum fortifies the material against localized corrosion, safeguarding integrity.
Iron (Fe): Limited to ≤5%, this ensures a perfect balance of strength and flexibility.
Our alloy exhibits exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC), making it ideal for use in acidic, alkaline, and chloride-rich environments such as marine and chemical processing.
Mechanical Strength:
Boasting high tensile strength (≥750 MPa) and impressive creep resistance, our alloy performs exceptionally under prolonged high-temperature stress.
Weldability:
Seamlessly compatible with GTAW (TIG), GMAW (MIG), and SMAW processes, ensuring versatility and ease of use.
Benefit from minimal post-weld cracking thanks to the low carbon content, enhancing reliability.
