Has anyone done crevice corrosion testing on duplex sst S32550 (25Cr, 5Ni, 3.5 Mo, .2 N, 2 Cu) or similar with welds in the as welded condition? We have not gotten good results in the HAZ in ASTM G48 method A tests unless solution annealed, but have never done crevice corrosion or chloride environment tests. How will the HAZ/weld stand up in these environments?

Groberts,

Have you asked on the Nace bulletin board ? I am sure you could find more info there. You have to sign-up for it ,but there is no charge.
I have corrosion data for Zeron 100 which is a super duplex in chloride containing waters, if you are interested ? If you are interested email me direct at Cstewart@noram-eng.com
