bolts/nutsin caustic or amine service.
bolts/nutsin caustic or amine service.
(OP)
We use SA193-B7M/SA194-2HM for Bolts and Nuts in H2S service. How about amine or caustic service. Can we use SA193-B7/SA194-2H for amine or caustic service?
Thanks

If the bolting is used for vessel internal (vessel in caustic service). Do we really need to use B7M?
Accoding to S Jones comments above, we do not need to worry about the caustic stress cracking for B7 bolting because there is no residual stress in the bolting material.
