Normalizing 516 gr 70 for use at high temperatures
(OP)
Is there any advantage to using normalized 516 gr 70 at temperatures around 800F?

RE: Normalizing 516 gr 70 for use at high temperatures
There is no significant advantage for using this pressure vessel steel in elevated temperature service. The reason is slightly lower creep strength in comparison to coarse-grained steels, which are tailored for use at elevated temperature service. The normalized steels are good for moderate to low temperature service.

BTW A515 is NOT a good choice for low temperature service.

Coarse grained material means fewer grain boundaries, which means fewer sites for creep void nucleation, which ultimately means higher creep strength.
