What Sets Monel 400 Plates Apart?
Monel 400 (UNS N04400, ASTM B127) is a solid-solution nickel-copper alloy, roughly 63% nickel and 30% copper, that holds its strength and corrosion resistance in highly aggressive environments like seawater and acid. It resists pitting, stress corrosion cracking, and biofouling, offering superior durability in marine hulls, pump shafts, and chemical reaction vessels.
This alloy’s excellent fatigue and impact resistance, combined with its weldability and machinability, enable fabricators to produce complex components with precision and reliability. Its ability to withstand temperatures up to 427°C (800°F) without loss of mechanical strength makes it invaluable for many industrial applications.
Aurico Alloys LLP provides Monel 400 Plates with full ASTM B127 certification, complete traceability, and quality assurance. Our extensive stock and flexible cutting services ensure your projects receive authentic, timely, and cost-effective solutions tailored to your operational needs.
