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 are micro-alloying elements, although the content is very low alloy steel elbow franchise, should bid out in steel. For example 20MnVB steel. Vanadium 0.07-0.12% 15CrMo alloy steel elbow, 0.001 to 0.005% boron. ④ High quality steel should finally add 'A' in the steel, 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 steel alloy steel elbow 30CrMnSi special offer, steel, said as ML30CrMnSi. Cangzhou Bohai Steel Tube Co., Ltd. specializes in the elbow called 16Mn 16Mn low-alloy high-strength structural steel junction high strength low alloy structural steel: carbon content of 0.1% and 0.25%, added to the main alloying elements manganese, silicon, vanadium, niobium and titanium and so on. 16Mn plate number of the old country, now it is classified as a high-strength low-alloy structural steel grades now known as Q345, Q345 steel but is 12MnV old number, a number of alternative types of steel 14MnNb, 18Nb, 16MnRE, 16Mn, etc. and not only substitute one material 16Mn steel. Alloy steel elbow manufacturers, alloy steel elbow, Ltd. Cangzhou Bohai Bohai Sea by Cangzhou tube. Cangzhou Bohai Tube Co., Ltd. (www.czbh628.com) (www.hbbh628.com) strong, credible, three-way, etc. Hebei Cangzhou accumulated a large number of loyal customers.
