16Mn (Q345B) pipe is a 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; 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. Where A, B grade steel 16Mn 16Mn usually called the chemical composition of steel: 16Mn Steel uses: special steel for the bridge as "16Mnq" q345b seamless spot, special steel automobile frames of "16MnL", pressure vessels The special steel for "16MnR". 16Mn Steel Standard: GB / T8162-2008 (structural) GB / T8163-2008 (transporting fluids) GB6479-2008 (high pressure seamless steel tubes for chemical fertilizer equipments) 16Mn steel weight calculation formula: [(OD - Wall Thickness) * wall thickness] * 0.02466 = kg / m (weight per meter) steel is to rely on the adjustment of such carbonaceous (C) amount to improve the mechanical properties of the steel, and therefore, according to the level of carbon content, such steels can be divided into : Low-carbon steel - carbon content is generally less than 0.25%, such as steel or the like 10, 20; the carbon - carbon content generally between 0.25 to 0.60%, such as steel or the like 35, 45; High-carbon steel - generally greater than 0.60% carbon content. Such is generally not used in the manufacture of steel pipe.
