Wuxi 16mn seamless, Katherine source Pipe (certified), Shantou 16mn provided by the source Pipe Co., Ltd. Liaocheng trillion. Source Pipe Co., Ltd. Liaocheng trillion (www.lczygg.com) is specialized in the "Q345b seamless steel pipe, 35crmo seamless steel pipe, 42crmo seamless" business, the company adhering to the "honesty, hard service" concept, for you provide the highest quality products and services. Welcome to inquire! Contact: Manager Wu. 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) 16mn thick-walled seamless steel pipe, according to the buyer need to provide 1800 Wuxi 16mn seamless cold bending test pipe, 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. Also provides + 200C when the impact energy Ak≥27J C-- same except with the Class B requirements, but also provides 00C impact energy Ak≥27J. When D ---- except with the Class B requirements like, but also provides -200C impact energy Ak≥27J E-- same except with the Class B outside 16mn seamless, it also provides impact energy when -400C 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.
