Maximum allowable stress 430A

[Spaceninja10]

I'm trying to find the maximum allowable stress for B.S. 1501-151 grade 430A , so that i can check the minimum allowable wall thickness for a vessel, built to an old standard.

Its ASTM equivalent would also be useful.

Thanks for any help

Hi

See this site its gives the yield stress for the above and from memory the safety factor is about 1.5.
