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 varieties company stocks 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, 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. 16Mn seamless steel pipe in one material for ABCD represents quality grade Q235 quality level is divided into A, B, C, D four, from A to D represents quality from low to high. Different quality level requirements are as follows: A-- provide S, P, C, Mn, Si chemical composition and fu, fy, δ5 (δ10), need to provide 1800 cold bending test according to the buyer, but no impact energy provision, carbon content and manganese content is not as delivery conditions. B-- provide S, P, C, Mn, Si chemical composition and fu, fy, δ5 (δ10), cold-formed 180 'trials. When the + 200C also provides impact energy Ak≥27J C-- except with the same outer q345b Class B seamless steel pipe prices, it also provides 00C impact energy Ak≥27J. When D ---- the same except with the Class B requirements, but also provides -200C impact energy Ak≥27J E-- same except with the Class B seamless steel outer q345b spot, it also provides -400C impact energy Ak≥27J. 16mn precision steel is high strength low alloy 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 "bent" pinyin word uppercase first, followed by figures for grades minimum yield point (σs) value. q345b seamless steel pipe use, Huludao q345b seamless steel pipe, steel pipe Katherine sources provided by the source Pipe Co., Ltd.
