What is Monel 405?
Monel 405, also known as Monel R405, is a nickel–copper alloy with excellent corrosion resistance and high strength. It is a free-machining grade of Monel 400, developed specifically for automatic screw machine operations. The added sulfur content in Monel R405 enhances its machinability without significantly affecting its strength or corrosion resistance.
This alloy is especially useful in environments where it is exposed to seawater, acidic solutions, alkalis, and other harsh chemicals. That’s why Monel R405 Sheets and Monel R-405 Coils are commonly used in marine, aerospace, and oil & gas applications.

As a reliable Monel R405 material manufacturer, ASC LLP provides Monel 405 Plates with the following outstanding properties:
- Superior Corrosion Resistance: Performs exceptionally well in marine and chemical environments.
- High Strength and Toughness: Suitable for high-pressure and high-temperature conditions.
- Excellent Machinability: Easier to machine than Monel 400 due to added sulfur.
- Thermal Stability: Retains mechanical properties over a wide temperature range.
