Monel 400 and Monel K500 are both nickel-copper alloys known for their excellent corrosion resistance and high strength. While they share some similarities, there are several key differences between Monel 400 and Monel K500, especially when it comes to their round bars.The addition of aluminum and titanium in Monel K500 provides enhanced strength and hardness compared to Monel 400.Monel K500 may have slightly lower corrosion resistance compared to Monel 400 in certain environments due to the presence of alloying elements.

Monel 400/K500 Round Bars Mechanical Properties
| Density | Melting Point | Elongation | Tensile Strength | Yield Strength (0.2%Offset) |
| 8.8 g/cm3 | 1350 °C (2460 °F) | 40% | Psi – 80,000 , MPa – 550 | Psi – 35000 , MPa – 240 |
In summary, Monel 400 and Monel K500 round bars are both excellent choices for applications requiring corrosion resistance and high strength. Monel K500 provides increased strength and hardness due to the addition of aluminum and titanium, while Monel 400 is widely used for its corrosion resistance and good mechanical properties. The selection between these alloys depends on the specific requirements of the application, considering factors such as strength, corrosion resistance, and operating conditions.
