FAQs

What are the key differences between Monel 400 and K500?

Monel 400 is a solid-solution alloy primarily composed of nickel and copper.   

Monel K500 is a precipitation-hardenable alloy.

It builds upon the Monel 400 composition with the addition of aluminum and titanium. This allows it to be age-hardened.

How does Monel 400 perform in seawater?

Monel 400 is highly resistant to corrosion in seawater and is commonly used for components that are exposed to marine environments, such as ship hulls and propellers, due to its ability to resist saltwater corrosion.

How are Monel 400 and K500 Round Bars machined?

Both Monel 400 and K500 can be machined using conventional machining methods such as turning, milling, and drilling. However, Monel K500 may require more specialized equipment or slower machining speeds due to its higher strength and hardness.

What is the hardness of Monel 400 and K500?

Monel 400 has a hardness of approximately 200 HB (Brinell Hardness).

Monel K500 has a significantly higher hardness, around 35-40 HRC (Rockwell Hardness C scale), due to its age-hardened properties.

How do you store Monel 400 and K500 Round Bars?

Both alloys should be stored in a dry, clean environment to avoid contamination or corrosion. It’s recommended to keep them in sealed packaging or containers to prevent exposure to moisture and other harmful elements.
