Brief introduction:
It's Ni-Mo alloy with additions of Fe, Co, Cr,and Mn.
It has excellent corrosion resistance in various reducing media and can withstand the corrosion of hydrochloric acid of any concentration at various temperatures under normal pressure.
It has excellent corrosion resistance in medium-concentration non-oxidizing sulfuric acid, phosphoric acid, high-temperature acetic acid, formic acid and other organic acids, bromic acid and hydrogen chloride gas, and is also resistant to corrosion by halogen catalysts.
It is commonly used in a variety of demanding petroleum and chemical processes, such as distillation and concentration of hydrochloric acid; alkylation of ethylbenzene and low pressure carbonylation of acetic acid and other production processes.
