Hello all,

I am designing a vessel for cryogenic service (-300 *F).
In the report, I receive a warning that the "Computed overall MDMT is higher than the required value." A review of the MDMT summary table shows that this is due to the nozzle bolting. I'm assuming that it has defaulted to A193 whereas I need A320 for this temperature range. However, after searching I can't find the option to change it!

I appreciate any help you can provide.
