Have you ever wondered what the difference is between Inconel and Monel Round Bars? Do you know what these two alloys are and what they are used for? Let us discuss the difference between the two round bars.
In the most basic terms Inconel is a nickel-chromium alloy whereas Monel is a nickel-copper alloy. Both metals are commonly used in applications with extreme heat, high temperature corrosion, and generally severe conditions.
Inconel 601 Round Bars
Inconel 601 Round Bars are nickel-chromium bars with an addition of aluminum for outstanding resistance to oxidation and other forms of high-temperature corrosion.” Inconel alloy 601 Bars have high tensile properties at room temperature and retains much of its strength at elevated temperatures. These characteristics specifically make Inconel 601 Round Bars an excellent choice for use in oil and gas extraction, among other applications. Typically, drilling for oil involves harsh conditions and requires products which can withstand these conditions. Inconel 601 Round Bars is the metal for the job in this case.
Inconel 601 Round Bars have outstanding oxidation resistance upto 2200 degrees F, good creep rupture strength, high resistance to carburization, resistance to spalling even under severe thermal cycling conditions, etc.
Inconel 601 Bars are used in chemical processing, construction, heat treatment industry, power generation, heat treatment of muffles and retorts, radiant tubes, nitric acid catalyst support grids, steam superheater tube supports, etc.
Monel 400 Round Bars
Monel 400 Round Bars are nickel copper alloy with high strength and excellent corrosion resistance in a range of media including sea water, hydrofluoric acid, sulfuric acid, and alkalies.” These properties make Monel 400 Bar an excellent choice for applications such as crude petroleum stills, chemical processing equipment, and gasoline and fresh water tanks, among other applications. You will see Monel 400 often used in salt water applications to its corrosion resistance in this environment.
Monel 400 Round Bars have Good mechanical properties from sub-zero temperatures up to 1020 degrees F, excellent resistance to stress corrosion cracking in most freshwaters, particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated, excellent resistance to neutral and alkaline salt, etc. Monel 400 is attacked in sulfur-bearing gases above approximately 700 degrees F and molten sulfur attacks the alloy at temperatures over approximately 500 degrees F.
Monel Alloy 400 bars have been commonly used in a wide range of industries and has been particularly useful in the marine and chemical processing industries. Typical uses include pumps and valves, propeller shafts, marine fixtures and fasteners, fresh and salt water tanks, electronic components, springs, chemical processing equipment, process vessels and pipes, boiler water heaters and other heat exchangers.
There are various other Monel and Inconel alloy grades which may be more suitable to your needs.
