Monel 400 nickel-copper alloy steel Description

Monel 400 nickel-copper alloy steel is renowned for its exceptional corrosion resistance and robust mechanical properties, making it a preferred material in demanding industrial environments. 
Monel 400 also known as UNS N04400 or Werkstoff Nr. 2.4360. Monel 400 copper-nickel alloy is widely used in marine engineering, chemical processing, oil and gas, aerospace, electronics and electrical industries.

Monel 400 nickel-copper alloy steel excels in environments where corrosion resistance is paramount. Its key performance attributes include:

• Superior Corrosion Resistance: Resists attack from seawater, hydrofluoric acid, sulfuric acid, and alkaline solutions, making it ideal for marine and chemical processing applications.
• High Strength and Ductility: Maintains mechanical integrity across a wide temperature range, from subzero to 1000°F (538°C), without undergoing a ductile-to-brittle transition.
• Excellent Weldability: Supports gas-tungsten-arc and resistance welding, with no need for post-weld heat treatment, enhancing fabrication efficiency.
• Moderate Machinability: While challenging due to rapid work-hardening, Monel 400 can be machined with proper tooling and low-speed techniques.
