According to GB/T 1591-2018 \"Low-alloy high-strength structural steel\", as of February 1, 2019, the steel grade Q345 was discontinued and replaced by Q355. I would like to ask whether the steel used for pressure vessels, Q345R, also needs to be changed to Q355R?

It depends on when GB 713 will be updated and whether there will be any changes

The container plate remains unchanged at Q345R for now.

Container panels and structural panels are not the same

When will the official revision be released? Does anyone know?
