3. Comparison with Monel 400
Monel K500 and Monel 400 are both nickel-copper alloys. However, the Monel K500 is stronger and has better work-hardening. This is because of the added aluminum and titanium.
These elements make Monel K500 much stronger and harder. This is especially true after age-hardening processes. This strength is important for uses that need high strength under mechanical stress.
Monel 400 is exceptionally good at resisting corrosion. It works well in slow-moving or still seawater.
This makes it a popular choice for marine uses. People often use it in seawater pumps, valves, and heat exchangers. In high-pressure and high-stress environments, Monel K500 stands out. Its strong mechanical strength and durability help it perform well in moving seawater.
People know both alloys for their great corrosion resistance. However, Monel K500 is special because it works well in fast-moving seawater. Applications that need more mechanical strength also show greater strength.
