Dear Mr. Herman
Thanks for quick reply.
It is not mistake in specification. Specification categorically demands 40% CaCl2 solution (Ph -6.5, Testing time - 500 Hrs., 100 Deg Boiling, Acceptance criteria - Stress to cause rupture shall exceed 0.85 times UTS, as per ASTM G 46)
Further, specification calls for MgCl2 solution for Duplex grade as per G 36.
Since, aberrant solution is being asked for testing as per ASTM G 36, precisely the question was put in this forum.
Request all team members to share views of chloride stress corrosion test of super Duplex ( S 32750)
With Best Regards,

Why does anyone asking for ASTM G36 with an aberrant test solution?
Probably there will be no big difference between both solutions
because Chloride is the important part in this test but by choosing
for CaCl you won't have any reference or acceptance criteria or is
this also specified in the project specification? Can it be a mistake
in the specification as well?
Best Regards,
Herman Pieper
