SA212-B had a basic allowable stress of 17,500 psi up to 650° (based on the 1962 and '65 codes). It was a 70 ksi UTS steel replaced by the SA515-70 and SA516-70 steels around 1967.
"Can anyone tell me the stress value for SA-212-B at 500 degrees F? I know that SA-212-B was discontinued in '62."
What is it that you are asking for? Do you want the yield stress for the material? Do you want the ultimate tensile stress for the material? Do you want the Code maximum allowable stress for the material? There is a different value for each of these for each Code. What are you going to design with this data? Piping, Pressure vessel, tank.....?
Good point, John. I defaulted to my own paradigm and listed the value for the basic allowable tensile stress for a Section VIII application along with the ultimate tensile at ambient.
Thank you. I forgot to specify what I was looking for. I was looking for the maximum allowable stress for the material at that temperature. It is for an exchanger shell put in sometime in the '40's.
Ok, for "sometime in the '40's" we need a bit more detail. The allowable stress I posted was for the '62 and '65 codes. These values were limited by UTS/4. The factor of 4 used to be 5. It was changed sometime around WWII to 4, then back to 5 before going to 4 with the 1950 edition. This remained 'till the '99 ed brought it to 3.5 (for the most part).
In the 1949 edition of VIII, S for SA212-B is listed at 14,000 up to 650°F.
