can carbide solution treated, strain-hardened SS be galvanized?
(OP)
If I specify A193 Grade B8 which is Carbide Solution treated and strain hardened, can I still galvanize it since heating after strain hardening is not permitted.

The zinc will cause contamination and could lead to corrosion cracking of the austenitic stainless steel components, when this two materials would come in contact. Any contact of SS with zinc should be avoided;- that includes even paint containing zinc, which accidentally may come from the painted carbon steel components located in vicinity of the stainless steel components.

Actually, the damage mechanism is liquid metal embrittlement of the austenitic stainless steel.

Are you saying that gr2vessels is incorrect about the zinc containing paint and contact between zinc and stainless steel?

If you are using a zinc-rich paint versus a galvanized bolt in contact with stainless steel stud, the only problem I see will be adhesion of the zinc-rich coating to the B8 stud material. Why worry about this problem? I would not apply any coating if it is not necessary. A galvanized bolt in contact with stainless steel is fine.
