Martensitic Bolts, ASME allowables

[rehfeld]

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)???

I have a fairly simple answer, look up the ASME II-D page 352-354 and select the appropriate value(s).
cheers,
