The 16Mn precision tube 16Mn precision tube has a carbon content of 0.1%-0.25%, and is added with main alloying elements such as manganese, silicon, vanadium, niobium and titanium; its total alloy content is <3%. According to the intensity, it is divided into four levels of 300, 350, 400 and 450 MPa. There are mainly Q295, Q345, Q390, Q420, Q460. : "Q" is the Chinese Pinyin uppercase head of the yielding "Qu" character, after which the number is the minimum yield point (σs) value of the grade, and the subsequent sign is according to the content of the impurity element (sulfur, phosphorus) of the steel. It is divided into A, B, C, and D by the change of carbon and manganese. Among them, A and B grade steels are usually called 16Mn.

The precision tube is a high-precision, high-brightness seamless steel pipe produced by cold drawing or cold rolling. The inner and outer diameters can be accurate to within 0.2mm, and the weight is light when the bending and torsional strength are the same, so it is widely used in the manufacture of precision mechanical parts and engineering structures. Also used to produce a variety of conventional weapons, barrels, shells and so on.

Shandong Huidong Chenglin Pipe Industry Co., Ltd. is located in Wuyishan Road, Liaocheng Development Zone, the largest steel pipe production base in Shandong. The company is a production, sales and processing enterprise.
