ASME SEC II, ALLOWABLE STRESS VALUE, HELP!!!!!!!!!
(OP)
Hi To all of you, Does anybody Knows The allowable Strees of High Alloy steel plate 18%Cr9%Ni type 304 at 500 F, according to ASME Sec. II part D. I need this data to evaluate the severity of measures in a thickness measurement inspection on pressure vessel. I only have sec. V and Sec VIII div 1, and I still haven´t found in my country an institution that posess sec II. If somebody Nkow it please write to me to falco@citt.cdb.edu.sv or to rfalconio@hotmail.com

In the site below, if you go to any of the ASME VIII sheets (under 'vessels'), you can choose a material and get the allowable stress.

I do not find a listing for 18% Cr 9% Ni in the tables. However, there is a listing for 18% Cr 8% Ni Type 304 Steel Plate: Max. Allowable Stress @ 500°F = 12.9 ksi
A well defined problem is half solved.

Which is the difference?
RE: ASME SEC II, ALLOWABLE STRESS VALUE, HELP!!!!!!!!!
I believe Appendix 1 of II-D provides the explanation for the two different stress values.

Tom123, read the notes associated with each line. I believe you will find the higher allowable stresses are not recommended for components that need to seal a fluid and might deform under load (like flanges or threaded connections).
