Product Introduction

Molybdenum-nickel alloy is an alloy composed of metal molybdenum as a matrix element and metal element nickel.

The common molybdenum-nickel alloys are NS322 nickel-molybdenum alloy material and Hastelloy B- 2(UNS N10665) nickel-molybdenum alloy material.

Advantages of Molybdenum-Nickel Alloy

Nickel molybdenum alloy NS322 carbon, silicon content is very low, reduce the welding heat affected zone of carbon and other impurity phase precipitation, so the weld also has enough corrosion resistance. NS322 has good corrosion resistance in reducing media, such as hydrochloric acid solutions of various temperatures and concentrations. In the medium concentration of sulfuric acid solution (or containing a certain amount of chloride ion) also has good corrosion resistance. It can also be used in acetic acid and phosphoric acid environments. Alloy materials can have the best corrosion resistance only when they are in a suitable metallographic state and pure crystal structure. It has a wide range of applications in the fields of chemistry, petrochemical, energy manufacturing and pollution control, especially in sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid and other industries.

Similar grades of NS322: Hastelloy B- 2 UNS N10665 (USA), NiMo28 (France), W.Nr. 2.4617 (Germany)
