Monel 400 is a solid solution strengthened alloy with excellent corrosion resistance. This alloy has better corrosion resistance than most alloys at room temperature, especially in flowing seawater. Therefore, Monel 400 is often used for parts in marine applications.
We manufacture Monel 400 round bar & rod according to ASTM B164. Regarding surfaces, we default to delivery in bright state. For the Monel 400 round bar, if you can accept a black bar, we can offer you the best price with a shorter lead time. For the Monel 400 rod, we can grind the material according to your requirements for higher precisio.
