Carbon steel bolts HDG used for 316SS flanges
(OP)
Hi,
Can anyone provide some assistance to the following:
Limitations in specifying ASTM A193 2H/A194 Gr. 2H bolts and nuts HDG in piping material classes 316SS dual certified ANSI 150 up to and including ANSI 900 DN 1/2" to DN 24".
Piping material classes in 316SS material dual certified have been specified for corrosion properties. Minimum design temperature for all 316SS piping material classes is (minus) - 29°C.
Thanks

It is somewhat common to use CS bolts in SS piping, even with the potential for galvanic corrosion. Usually, they'll specify the use of Galvanized or Tropicalized CS bolts.
