The new standard code for 16Mn steel pipes is now Q345D

Isn’t Q345D listed in the standards either?

In my opinion, 16Mn as specified in 6479-2008 and Q345B as specified in 6479-2013 are not equivalent; there is a difference when it comes to low-temperature impact performance； It should be said that the material specified in BaYuan 16Mn 6479-2008 has been further divided into Q345B, Q345C, Q345D, and Q345E.
