Yes, it can withstand impacts at -20° Celsius. Doing insulation again shouldn’t be a problem!

This material cannot be used in atmospheric-pressure equipment either

In my opinion, Q235B should not be used; instead, the material Q345R should be employed.

Check the provisions in GB50341.

According to Appendix D of GB/T150.2, the operating temperature range for steel plates made of Q235B material is 20°C–300°C; therefore, Q235B cannot be used.
