Nickel molybdenum is an alloy that plays a vital role in various corrosion-resistant applications. Its properties make it suitable for a variety of products including piping, pressure vessels, gaskets, and other chemical processes.

Typically, nickel-molybdenum alloys are known for their high resistance to acid-corrosion. They are characterized by a low coefficient of expansion and an excellent formability. A new nickel-molybdenum-chromium alloy has been developed for the chemical process industry, as it exhibits good resistance to chloride-induced localized attack.

The HASTELLOY alloy B-2 is a very high-performance alloy that is particularly resistant to hydrogen chloride and reducing acids. In addition, the B-2 has a superior resistance to slightly oxidizing conditions.

Various other nickel-molybdenum alloys have been developed, ranging from alloys with higher chromium content to those with lower iron contents. Some of the alloys are sold under the trade names Inconel 617(r) and Nicrofer(r) 617.

These alloys are commonly used in a wide range of industries, including the petrochemical industry, the chemical industry, and the energy industry. Especially in the petroleum industry, nickel-molybdenum oxide is used as a catalyst. This alloy can be used for chemical reactions such as the reduction of hydrogen into water.

Another popular nickel-molybdenum alloy is Alloy B-2. This alloy contains 29-30% molybdenum and is used in a number of piping systems. To improve its stability, it is tempered with iron to enhance resistance to mild oxidation.

Alloys C-22, 59, and 686 have also been introduced. These alloys were developed in the 1980s to improve corrosion resistance in acid-chloride environments.
