Dec 04, 2020 · Q345 steel is the replacement of the old grades of 14MnNb, 12MnV, 16MnRE, 16Mn, 18Nb, and other steels, not just the replacement of 16Mn. In terms of chemical composition, 16Mn and Q345 are also different. More importantly, there is a big difference in the thickness grouping size of the two steel materials according to the different yield strength, The difference between steel pipe material 16Mn and Q345 Q345 steel is the oldest 14MnNb, 12MnV, 16MnRE, 16Mn, 18Nb, and other steel alternative, rather than just replace a 16Mn steel. In the chemical composition, 16Mn and Q345 are also different. More importantly, the thickness of the two kinds of steel by the yield strength of the thickness of the packet size there is a big difference, which will lead to some thickness of the
