Is it permissable to use a suppliers material strength values rather than the ASME section II material strength values when doing pressure vessel thickness calcs. The suppliers material strength values are higher!
I am looking to design a vessel with S275 JR steel which is covered by EN 10025-2:2004. However this grade steel is not an option on the Finglow software. Do I use the closest matching material in this case?
I would like to be able to match the old BS steel numbers to the ASTM and the EN numbering system, is there somewhere that I can find this info all in the one place. Thanks
