MONEL K500, also known as UNS N05500, has the same corrosion resistance as Aloy 400, but has higher mechanical strength and hardness. It has good heat corrosion resistance and long-term organizational stability.
Monel 400 is a single phase solid solution Ni-Cu alloy, which has good corrosion resistance in many media environments. From a slight oxidizing medium environment to a neutral environment, to a suitable reducing environment, it has good corrosion resistance. Such alloys have a long history of use as corrosion-resistant materials.
