Regarding the yield strength of Q235-B
Thread Content
Why does Q235-B not have a yield strength value at 200 degrees? In GB150 as well, the yield strength value for Q235-B at 200 degrees is also left blank. Why? If any expert knows, please advise!
Is your 150 different from mine? The yield strength at room temperature is simply 235
It’s the same; I mean, there’s no value at 200 degrees
The temperature is too high; it’s best not to use Q235-B, so the value at 200 degrees has little practical value.
Is the yield strength still the allowable stress at 200 degrees? Yield strength refers to plastic deformation at room temperature; if it were the allowable stress, then there would be a value even at 350 degrees
