UNS N10675 Corrosion-Resisting Superalloy Bars and Plates
This high nickel-molybdenum austenitic corrosion-resistant alloy possesses outstanding resistance to strong reducing acids. With low impurity content and stable single-phase structure, it has superior hot & cold formability and weldability, good resistance to stress corrosion cracking in reducing media, ideal for pressure-bearing equipment under heavy reducing corrosion.
Applications of UNS N10675
Widely used in hydrochloric acid reactors, hydrometallurgical leaching tanks, complete pickling equipment, phosphoric acid concentration heat exchangers, hydrofluoric acid treatment units and strong-reducing corrosion reactors for organic synthesis, serving as a dedicated pressure-bearing alloy for service environments with high-concentration reducing acids.
