U can carry out PWHT as per table   UCS 56.1 - Decrease the temperature  & increase the soaking time.

Codes are not handbooks. Metallurgy knowledge is necessary.

In general CS needs to be buttered with an alloy which is not sensitive to sensitization from one part and from the other part does not give low FW. Then PWHT is performed and then SS us welded
