Advantages and Disadvantages of ASTM B165
Advantages:
Monel 400 is highly resistant to corrosion from seawater, ammonia, and various acidic environments, making it suitable for high-temperature, high-pressure applications.
Disadvantages:
Due to its alloying elements, Monel 400 is more expensive than carbon steel or stainless steel. Additionally, it is more difficult to machine and weld due to its high strength and hardness. Monel 400 also has poor corrosion resistance to some strong acids, such as hydrofluoric acid.
