Issues regarding the thickness of use for Q345R
Thread Content
I was wondering if anyone knows whether a thickness of 240 mm is feasible for Q345R, and if there is any evidence to support this
The thickness of Q345R can reach 240 mm. Haven’t seen it.
Sure, we have already used our high-temperature resistant containers
It cannot be used on pressure vessels, but it can be used for structural components. Why don’t you use Q420R or a higher-strength steel with greater strength?
Is it high temperature or high pressure that you need, and what wall thickness is required?
It should be possible; the hydrogenation reactors made of chromium-molybdenum steel used in refineries are generally over 300 millimeters in thickness, so Q345 should work fine. However, with a thickness of 240 mm, it is likely that forgings will be necessary.
It might not be Q345R then. 16MnⅡ forging material. The thickness is just that thick.
