Seamless 16mn Alloy Steel Pipe
low alloy structural steel pipe
16Mn alloy steel pipe is a low-alloy high-strength structural steel with a carbon content of 0.1%-0.25%, and the main alloying elements manganese, silicon, vanadium, niobium and titanium are added; its total alloy content is less than 3%. According to the intensity, it is divided into 4 levels: 300, 350, 400 and 450MPa. Mainly include Q295, Q345, Q390, Q420 and Q460.
Chemical composition of 16Mn seamless alloy steel pipe: C: 0.12~0.20; Mn: 1.20~1.60; Si: 0.20~0.55; Tensile strength: 470~660 N/mm2; Yield strength: 275~345 N/mm2; Elongation: 21%. Thickness or diameter: 16~100mm.
16Mn alloy steel pipe is a low-alloy high-strength structural steel: "Q" is the Chinese pinyin for "yield", and the following numbers are the minimum yield point (σs) value of the grade, and the following symbols are according to the steel The content of impurity elements (sulfur, phosphorus) is divided into four grades: A, B, C, and D from high to low with changes in carbon and manganese elements. Among them, A and B grade steel are usually called 16Mn.

Seamless 16mn Alloy Steel Round pipes
According to different uses and needs, 16MN seamless pipes can be divided into structural seamless pipes, hydraulic seamless pipes, petroleum cracking seamless pipes, etc. Structural seamless pipes are mainly used for supporting structures and transporting fluids in construction and bridge projects; hydraulic seamless pipes are mainly used for hydraulic systems in engineering machinery and hydraulic equipment; petroleum cracking seamless pipes are mainly used for oil and natural gas Transport pipelines in industry.
There are two main manufacturing processes for 16MN alloy seamless pipes: hot rolling and cold drawing. The hot-rolling process is to heat 16MN alloy structural steel to a certain temperature and then roll it to form a seamless pipe; the cold-drawing process is to cold-draw the hot-rolled steel pipe to further improve dimensional accuracy and surface quality
