SA-105 Flange_MDMT -20°F

[Mechanical1991]

Hi all,
I have a question about SA-105 material
According to ASME VIII Div 1 2019, the SA-105 material belongs to Curve A (before it belonged to curve B), which does not reach up to -20°F MDMT. Can I apply Figure UCS-66.1 to reduce the temperature to reach MDMT -20°F?

Thanks for your comments
