China Hastelloy Pipe manufacturers Description Of Hastelloy B2 Round Tubing Found in the industrial application of Hastelloy B2 round tubing for many years: Hastelloy B2 round tubing has poor thermal stability at medium temperature. When the iron content in Hastelloy B-2 alloy drops below 2%, the alloy is sensitive to the transformation of 尾 phase (ie Ni4Mo phase, an ordered intermetallic compound). When the alloy stays in the temperature range of 650~750鈩?for a little longer, 尾 phase is formed instantaneously. The existence of 尾 phase reduces the toughness of Hastelloy B-2 alloy, making it sensitive to stress corrosion, and even causes Hastelloy B-2 alloy in the production of raw materials (such as hot rolling) and equipment manufacturing processes (such as The overall heat treatment of Hastelloy B-2 alloy equipment after welding) and Hastelloy B-2 alloy equipment cracked in the environment. Nowadays, the standard test method for the resistance of Hastelloy B-2 alloy to intergranular corrosion designated by countries all over the world is the atmospheric boiling hydrochloric acid method, and the evaluation method is the weightless method. Since Hastelloy B-2 alloy is an alloy resistant to hydrochloric acid corrosion, the normal pressure boiling hydrochloric acid method is quite insensitive to the intergranular corrosion tendency of Hastelloy B-2 alloy. Research institutes used high-temperature hydrochloric acid to study Hastelloy B-2 alloy and found that the corrosion resistance of Hastelloy B-2 alloy not only depends on its chemical composition, but also depends on its thermal processing control process. When the hot working process is improperly controlled, the Hastelloy B-2 alloy not only grows grains, but also a high-Mo 蟽 phase will be precipitated between the grains. At this time, the resistance of Hastelloy B-2 alloy to intergranular corrosion is significantly reduced. In the high-temperature hydrochloric acid test, the grain boundary erosion depth of the coarse-grained plate and the normal plate is about twice as long.
