crevice corrosion testing of duplex to G78
crevice corrosion testing of duplex to G78
(OP)
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?
