ASTM A312 Hastelloy Pipe Description Of Hastelloy B2 Seamless Tube Hastelloy B2 is a solid solution strengthened nickel-molybdenum alloy, which has significant resistance to reducing environments (such as hydrogen chloride gas, sulfuric acid, acetic acid and phosphoric acid). Molybdenum is the main alloying element and can provide significant corrosion resistance for reducing environments. As we all know, Hastelloy B2 seamless tube has excellent corrosion resistance in various reducing media, and can withstand the corrosion of any temperature and any concentration of hydrochloric acid under normal pressure. It has excellent corrosion resistance in non-aerated medium concentration of non-oxidizing sulfuric acid, various concentrations of phosphoric acid, high temperature acetic acid, formic acid and other organic acids, bromic acid and hydrogen chloride gas. At the same time, Hastelloy B2 seamless tube is also resistant to halogen catalysts Corrosion. Therefore, Hastelloy B2 seamless tube is usually used in a variety of harsh petroleum and chemical processes, such as the distillation and concentration of hydrochloric acid; the alkylation of ethylbenzene and the low-pressure oxo acetic acid production process. Hastelloy B2 seamless tube has poor corrosion resistance to oxidizing environment. Therefore, it is not recommended to use it in oxidizing media or in the presence of iron or copper salts, as they may cause premature corrosion failure. Hastelloy B-2 alloy has two sensitized zones that have a considerable impact on the resistance to intergranular corrosion: a high temperature zone of 1200~1300鈩?and a medium temperature zone of 550~900鈩?
