Hey Everyone,
I have what seems to be a fairly simple question. If I have martensitic precipitation-hardening stainless steel bolts, which ASME subsection NF-3324.6 tension allowable should I use (it gives one allowable for austenitic and one allowable for ferritic)???

ASME gives values for the Design Stress Intensity value, Sm, in Table I-1.3 from Section III Division 1 for A564 Type 630 bolt material so I assume is commonly used. The question I am really asking is the allowables given in NF-3324.6 defines seperate allowables for ferritic (Su/2 for...
