Steel pipe knowledge: 16Mn (Q345B) seamless steel pipe knowledge
16Mn (Q345B) seamless steel pipe is a low-alloy high-strength structural steel, carbon content of 0.1% -0.25%, adding the main alloying elements manganese, silicon, vanadium, tantalum and titanium, etc.; its total alloy content <3%. It is divided into four levels of 300, 350, 400 and 450 MPa according to intensity. There are mainly Q295, Q345, Q390, Q420, Q460. : "Q" is the Chinese Pinyin capitalized initial of the yielding "Qu", and the subsequent number is the value of the minimum yield point (σs) of this grade. The following symbol is based on the content of the impurity elements (S, P) of the steel. It is divided into A, B, C, and D grades when it is low and changes with carbon and manganese. Which A, B grade steel is usually called 16Mn.
