Xiangfan q345b seamless, cold drawn seamless q345b, Katherine source provided by Liaocheng Steel Pipe Co., Ltd. Katherine source. Xiangfan q345b seamless, cold drawn seamless q345b, Katherine source Steel Pipe Co., Ltd. is the source of Liaocheng trillion (www.lczygg.com) launched this new upgrade, the above picture is only for reference, please call or pictures on this page on the telephone, obtain the latest information, contact: Manager Wu. 16Mn (Q345B) pipe is a low alloy high strength structural steel, carbon content of 0.1% -0.25%, to join the main alloying elements manganese, silicon, vanadium, niobium and titanium; its total alloy containing <3%. 300,350,400 divided by strength and 450MPa and other four levels. There are Q295, Q345, Q390, Q420, Q460. : "Q" is the yield of the "bend" the word Pinyin big write head, followed by figures for grades minimum yield point (σs) value. Where A, B grade steel 16Mn 16Mn usually called the chemical composition of steel: 16Mn Steel uses: special steel for the bridge as "16Mnq", a special steel automobile frames of "16MnL" q345b seamless pipe prices, pressure vessels The special steel for "16MnR". 16Mn Steel Standard: GB / T8162-2008 (structural) GB / T8163-2008 (transporting fluids) GB6479-2008 (high pressure seamless steel tubes for chemical fertilizer equipments) 16Mn steel weight calculation formula: [(OD - Wall Thickness) * wall thickness] * 0.02466 = kg / m (weight per meter) steel is to rely on the adjustment of such carbonaceous (C) amount to improve the mechanical properties of the steel, and therefore, according to the level of q345b seamless carbon content, such steel can be divided into: low carbon - carbon content is generally less than 0.25%, such as steel or the like 10, 20; the carbon - carbon content generally between 0.25 to 0.60%, such as steel or the like 35, 45; High carbon - carbon content is generally greater than 0.60%. Such is generally not used in the manufacture of steel pipe. Main various 16mn seamless, geological pipe, large diameter seamless steel pipe, precision steel, galvanized seamless steel, 40cr steel pipe, steel pipe, stainless steel, carbon steel pipe, ductile iron pipe, pipe fittings and welding materials and so on. Large company stocks a full range of low prices. Shandong Liaocheng seamless steel pipe plant located is known as "Jiangbei Water City" reputation of Liaocheng City Development Zone in Shandong Province, is located in the country's largest seamless steel distribution center - Big East steel market, north of Qingdao - Jeju Museum along the highway, Beijing Kowloon Railway runs through north and south, location and convenient transportation. As Shandong's largest seamless steel pipe plant q345b factory, our company has independent right to import and export business agent for customers and agents seized, steel exports to other countries and regions in the United States, Pakistan, Egypt and other countries.
