Duplex SS for SRB corrosion
Duplex SS for SRB corrosion
(OP)
I have a question regarding the metallurgy for SRB corrosion protection. It was extensively reported that SRB corrosion can eat stainless steel and casue localized corrsoion, like 304L. I am wondering if duplex SS has the same problem in SRB enviroment? Since it is harder than austenite alloys. Thanks.

The strength or hardness of the alloy has no role in this.
It is simply the chemical stability of the alloy.

The F/M SS are martensitic stainless alloys that don't fully harden. Different animals all together and not referred to as duplex.

You have asked for Duplex SS SRB corrosion. The comments have slided off the track. The Duplex Stainless Steel is the ferrite and austenite alloy at approx 50% (ideally).
Yes, it can be affected by SRB, under specific conditions. Look up the NACE MR0175 for restrictions of use, also check out reputed studies available on the internet. Refer also to the Outokumpu corrosion handbook for further guidance.
