B31.3 - Heat Treatment

[Jeldon]

Hello friends, greetings. I need help.
I have a weld metal with base P No. 1, that the throat is 17.0 mm, in accordance with paragraph 331.1.3 (b) (1) of the code ASME B31.3, where the temperature should be used?

For a throat of 17mm, you need to look at Table 331.1.1 for P-No 1 base material, the PWHT temperature is 593-649 deg C.
