16Mn called low-alloy high-strength structural steel high strength low alloy structural steel: carbon content of 0.1% -0.25% 16mn thick-walled seamless steel pipe, adding the main alloying elements manganese, silicon, vanadium, niobium and titanium; alloys containing it the total amount of <3%. 300,350,400 divided by the intensity and 450MPa and other four levels. There are Q295, Q345, Q390, Q420, Q460. : "Q" is the yield of the "Qu" pinyin word uppercase first, followed by figures for grades minimum yield point (σs) value, followed by the symbol is in accordance with the steel impurity elements (sulfur, phosphorus) content by high accompanied by changes to the low carbon, manganese and is divided into A, B, C, D four and so on. Where A, B grade steel usually called 16Mn.
