Cangzhou Bohai Pipe Co., Ltd. specializing in the production of alloy steel elbow vanadium steel V, Ti Ti, Al AL, boron B, rare earth RE alloying elements such as steel elbow, are micro-alloying elements, although the content is very low bending steel sales head, should bid out in steel. For example 20MnVB steel. 0.07-0.12% of vanadium, 0.001 to 0.005% boron. ④ High quality steel should finally add 'A' 15CrMo alloy steel elbow, as distinct from the general high quality steel. ⑤ special purpose alloy structural steel, and steel dubbed (or suffix) represents the symbol of the steel use. For example riveting Lo 30CrMnSi special steel, steel, said as ML30CrMnSi.
