SA-387 9 Chrome Plate
SA-387 9 Chrome Plate
(OP)
Hi Guys,
I am designing a unit to ASME Section VIII-1 that is 9 Cr-Mo. I found all the other forms in Section II-D but the stress values are not there for plate. I checked in Section II-A under SA-387 and I did find grade 9 so it is an approved material.
Any thoughts or ideas how I am to perform calculations on this material form?
Please advise,

A material must be listed and permitted in Sec II, Part D for a given Sec & Div to be used under the same. Presence in a material spec is not relevant.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Grade 91 is a different material with a different P-no. It is not really interchangeable.
I have contacted my inspection agency for their thoughts.

My customer has allowed me to use Grade 91 Chrome for all materials so this point is moot, but I thought I would follow up with you guys.
