Hello

I need to work on some old vessels and require the allowable stresses of SA201-A at 100F and 825F and SA201-B at 100F and 500F, Can anyone help?

Thanks in advance

SA201-A at 100F and 825F

100 deg F 13,750 psi
800 deg F 10,200 psi

SA201-B at 100F and 500F

100 deg F 15,000 psi
500 deg F 15,000 psi

For SA-201 Grade A at 850 deg F the allowable is 7,800 psi. So, you can do the interpolation yourself. The 850 deg F is also when time dependent properties dominate.
