Classification Method of Q345B Seamless Steel Pipe

Oct 17, 2019 · The Q345B steel tube represents the carbon content of this steel in the range of about 0.16%. Mn alone was proposed because the five elements (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S) have high manganese content and are proposed separately.
