Jiangsu, Gansu 16Mn 16Mn seamless factory direct factory outlets seamless 16Mn 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; it's total alloy containing <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) at levels ranging from high to and is accompanied by changes in the low carbon manganese divided into A, B, C, D four and so on. Where A, B grade steel usually called 16Mn. The company is one of 16Mn seamless steel seamless million households big agreement, with long-term production of seamless steel pipe plant in Liaocheng diameter seamless steel pipe, seamless pipe purchase large, you can prioritize Liaocheng Xin Hong Shun steel company, and the company's major steel mills run pipe, galvanized steel pipe, spiral steel pipe, square and rectangular steel pipe, standing resource material for the: 20 #, 45 #, 16Mn, Q195, Q235B and so on.
