Monel R405
Description
Monel R405 is a free-machining grade of Monel 400, with similar strength and corrosion resistance but better machinability due to added sulfur. It’s great for high-speed machining and is used to make valves, fasteners, and instrument parts. It also performs well in cold-bending applications.
Application：
- Pump shafts and impellers
- High-pressure vessels
- Piping and heat exchangers
- Drill collars and
- instruments
- Marine environments
