New China Standard-Q345B Changed to Q355B

As we all know, China's steel production is the largest variety of rebar, followed by steel plate and sheet, and the largest percent of steel grade produced in the plate is Q235B, followed by Q345B. The biggest impact of the new GB/T 1591-2018 release is Q345B , because the output of other grades has little effect.

Q235 vs Q345 Strength? - Structural engineering general

Sep 28, 2010 · There are also different 4 grades of Q235 and 5 grades of Q345 which have varying carbon content. The PRC Steel Design Code GB 50009 uses a value of E = 206,000 MPa (29,877,774 psi). Perhaps the steel mill in China could provide you with some more specific material data. Q345 steel property and specification are equivalent to Q345 steel is one kind of Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, used for a number of manufacturing purposes. To some extent, the Q345 possesses the same property and composition of ASME A572, namely the Q345 is equivalent to A572. This specification covers the standard requirements for
