SA-212-Grade B

SA-212-Grade B

SA-212-Grade B

I could really use some help in obtaining stress levels of SA-212-B at 650F and 1000F. Can anyone please help?
Thanks very much!

RE: SA-212-Grade B

At 650 deg F  17.5 Ksi
At 1000 deg F  1.5 Ksi (hint: should not be used at this service temp)!

Source Section I, 1952

RE: SA-212-Grade B

Thank you so much for your response. What I am curious about is that the substitute for SA-212-B which is SA-515-70 has an
allowable stress of 2500 psi at 1000F, but yet you say that it is only 1500 psi for SA-212-B; this really throws my calculations way off. Would you be so kind as to please verify this for me and if so, would it also be possible to please look up the stress values for SA-212-B at 700, 750, 800, 850, 900 and 950?

With much appreciation,

RE: SA-212-Grade B

Keep in mind that SA 212 Grade B is not exactly the same as SA 515 Grade 70. The SA 212 plate was discontinued as steel-making practices improved, and there was a desire for coarse-grained material with higher elevated temperature strength to manufacture steam drums and other boiler components.

700    16.6 ksi
750    14.75 Ksi
800    12 ksi
850    7.8 ksi time dependent properties control allowable stress
900    5 ksi

RE: SA-212-Grade B

You are fantastic and a credit to our profession!
I know that I am being presumptuous but would it be possible for you to help me with just one more material: SA-301-B.
I need stress values at 800F, 750F, 700F, 650F to room temperature. I am sorry to indulge your kindness and I hope that some day I may return the favor.
With extreme appreciation and thankfulness!
