304H Pressure Vessel MDMT

I use PV-Elite to generate my code calculations section VII div 1 and it is not creating the MDMT summary for my vessel of 304H material. Is it not required by code to perform MDMT calcs. for 304H material?

hawksy, consideration of MDMT is required for all materials, if your software won't do it, you'll have to. See UHA-51. Also, if your software does give you an MDMT summary, don't swallow it whole.

Thank you.
Based on this my understanding is that per UHA51(d) No Impact Testing is required because my required MDMT is 20deg.F and the carbon content of 304 H is not to exceed 10%.

hawksy, that sounds about right, but confirm you are not under UHA-51(c)
