What is the difference between inconel and monel

Oil and Gas Extraction, aerospace, and pharmaceutical application are great examples of industries that would require Nickel Chromium or Inconel. Nickel Copper, however, is great for corrosion resistance. Their notable strengths would be against sea water, both hydrofluoric and sulfuric acids, as well as alkalies and harsher acids. These strengths play to the trades of chemical processing, sea refineries, oil refineries, as well as coastal structures.

If you work in these fields, you will benefit from the Nickel Copper or Monel alloys. Regardless of heat transference and corrosion resistance, there are other factors that will affect your purchase of either. As a manufacturer we can provide customized products for any application.

If you have any questions or wish to learn more about our products and capabilities, visit our product specific pages or contact us. Do you know what these two alloys are and what they are used for? Both metals are commonly used in applications with extreme heat, high temperature corrosion, and generally severe conditions. Typically, drilling for oil involves harsh conditions and requires products which can withstand these conditions.

Inconel has higher oxidation resistance than monel where the Monel grades have resistance against sea water and reducing media such as hydrofluoric acid, sulfuric acid and alkalis. The corrosion resistance of Inconel under high temperatures makes it possible to be used in elevated temperature applications with the possibility of oxidation. The monel on the other hand can be used in sea water, marine, chemical and acid producing industries.

Both materials have similar melting points. The Inconel melting point ranes from degrees Celsius to degrees Celsius. Monel grades have melting points ranging from degrees Celsius to degrees Celsius. Although the melting points are similar the Monel alloys have higher toughness which make them useful for wear and tear resistant applications. Monel has higher densities than the Inconel due to the high nickel copper composition. Inconel has nickel but the chromium combination reduces the density a little bit lower than that of Monel.

Yet, Monel can withstand all concentrations of hydrofluoric acid, even up to the boiling point. In hydrofluoric acid, Monel and Hastelloy C are leaders in protection. It is recommended that Monel is most suitable when fully immersed.

Keep in mind aeration or the presence of oxidizing salts will increase the corrosion rate. Here Inconel does not perform as well, making Monel the better choice. Economic Seawater Protection Both Monel and Inconel perform extremely well in salt water environments. The only difference is that Monel can experience pitting corrosion in stagnant sea water, though the progression of pitting slows tremendously after the initial attack.

Yet, Monel shows superior performance in rapidly moving seawater, which makes it a material of choice for the Navy. As both are highly resistant, we often suggest Monel , as Inconel is more expensive and often overkill for many marine environments. Great post easy to understand the difference because of chart showing the difference keeping share such information.
