Product Description

16Mn low-alloy steel pipe is: 16Mn is called low-alloy high-strength structural steel Low-alloy high-strength structural steel: the carbon content is 0.1%-0.25%, and the main alloying elements manganese, silicon, vanadium, niobium and titanium are added; its total alloy content is <3%. According to the strength, it is divided into 4 levels of 300, 350, 400 and 450MPa. There are mainly Q295, Q345, Q390, Q420, Q460. : "Q" is the uppercase prefix of the Chinese pinyin of the word "Qu" for yield, and the subsequent number is the minimum yield point (σs) value of the brand, and the subsequent symbols are divided into A, B, C, D, etc. according to the content of impurity elements (sulfur, phosphorus) in the steel from high to low and with the change of carbon and manganese elements. Among them, A and B grade steel are usually called 16Mn.


The special steel grade used for bridges is "16Mnq", the special steel grade for automobile girders is "16MnL", and the special steel grade for pressure vessels is "16MnR".

16Mn is applied to manufacture factory building, civil building and all kinds of engineering machinery in mine industry and various of civil construction, such as drilling rig, electric shovel, powered wheel tipper, mining vehicles, excavators, loaders, bulldozers, industrial blowers, various types of cranes, mining machinery and equipment,such as hydraulic support and other structural parts.
