　　Q345B seamless pipe is one of the steel materials. In the past, steel was called 16Mn.

　　16，The carbon content of the steel is about 0.16%. However, Mn is proposed separately because of the high content of manganese in the five elements (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur s). Q345B seamless pipe about 1.20-1.60%.

　　Q345B alloy steel pipe belongs to low alloy steel plate series. In this series, it is the most common material or brand steel plate.

　　According to the special requirements, some special treatment can be carried out on the steel plate: heat treatment and Z-direction performance.

　　ASTM A106 Grade B 3PE Coated Seamless Pipe has good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability.

　　Application examples: mining, transportation, chemical and other machinery.

　　Q345B seamless pipe weight formula: [(outer diameter wall thickness * wall thickness] * 0.02466 = kg / M (weight per meter)
