Detailed Description
16Mn steel commonly known as 16 Mn steel, also known as high-strength low-alloy structural steel, and its carbon content is 0.1% -0.25%, adding the main alloying elements manganese, silicon, vanadium, niobium and titanium; its total with alloy <3%. The intensity of 300,350,400 and 450MPa by other four levels. There are Q295, Q345, Q390, Q420, Q460. : "Q" is the surrender of the "wrongly accused" big write the first word of the pinyin, then figure the minimum yield point for the grade (σs) value, then the symbol is in accordance with the impurities in the steel (S, P) content by high- to low and with carbon, manganese changes were divided into A, B, C, D 4 and so on. Where A, B grade of steel usually called 16Mn, the materials used do not only for the 16Mn steel pipe noted in .16 Mn steel making process can be divided into different seamless and welded steel 16Mn 16Mn steel. Which 16Mn steel welded straight seam steel pipe can be divided into 16Mn, 16Mn spiral steel pipe, 16Mn steel square moment.
