JStephen: Thanks, that clears things out... The reason I needed those stress values is to evaluate pressure vessels currently in use... would other codes be applicable here ? If so, can you specify which ones, or do you need more informaiton ?
Thanks

curtis2004: To my understanding, SA metals in the US are made according to chemical compositions specified in the present ASME code, so if the metal was made a long time ago, they must have used the ASME code of that time.... and hence the allowable stresses would be different....
however, if...
Thanks mengnr, appriciate the help.... quick question though.... the code your referring to, when was it published ? .... I think I need the code published in 1992, or somewhere around that time, because thats when the vessel was built....
Once Again, Thanks
Hi,
Just starting out as an Engineer... I don't have access to all ASME Sec 8 published to date and I needed allowable stresses for the following materials...
SA-516 Gr 70 built 1998 Temp. -20 to 100 F
SA-240 Gr 304 built 1993 Temp. -94 F
SA-516 Gr 70 built 1974 Temp. less than 150...
