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. 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. D ---- When the same except with the Class B outside 16mn steel, but also provide -200C impact energy Ak≥27J E-- same except with the Class B requirements, but 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 "bend" the word Pinyin big write head, followed by figures for grades minimum yield point (σs) value. 16mn, Ningbo 16mn, Katherine source provided by Liaocheng Steel Pipe Co., Ltd.
