The relationship between 16Mn seamless steel tubes and Q345B seamless steel tubes Alloy 16mn seamless steel tubes were originally a material in steel. A name for steel in the past. The current name is Q345B seamless steel pipe due to 16Mn seamless steel pipe, which represents the content of carbon in this steel is about 0.16%. However, Mn is proposed separately because the contents of five elements (carbon C, silicon Si, manganese Mn, phosphorus P, and sulfur S) are high, and they are proposed separately. About 1.20-1.60%.
16Mn is a series of low alloy steels. In this series, it is the most common material or grade of steel.
According to special requirements, the steel plate can be subjected to some special treatments: heat treatment and Z-direction properties.
