Allowable stresses of A182 F316 forged fitting with thickness below 5 in. per B31.1 1

[Fred19]

Hello folks,
I am doing the calculation for stainless steel piping with a temperature/pressure rating 400F/4000psi based on B31.1.
B31.1 note(12) for A182 F316 indicates "These allowable stress values apply to forgings over 5 in. in thickness." One interpretation of this note would be that the code does not permit the values of A182 F316 allowable stresses to be used for forged fittings below 5 in. thickness, in my case 3/8" socket tee. In the other word, the designer must use F316L allowable stresses for all forged fittings below 5" in thickness.
Am I understanding the note correctly? It looks odd to not be able to use F316 allowable stresses in the calculation for small fittings at 400F.

There are other entries without note 12.

Thank you David. I noticed that I can use other entries for that material.
Appreciated.
