Stainless steels were the first materials to be tested for possible use as reactor-material for SCWO facilities, because of their corrosion resistance at normal temperatures and their relatively low costs. Stainless steel can be used at T<400 °C provided that the feed be free of chloride, or that it is present at low concentration [18]. Acidic pH is known to accelerate corrosion, and at basic pH it suffers stress-corrosion cracking . 

The possibility of sulfide stress corrosion cracking, including consideration of the possibility for future H2S occurrence even though it is not presently contained in the produced fluids is not addressed in this procedure. If sulfide stress corrosion cracking is a concern only resistant carbon or low alloy steels are included in the corrosion testing. The consideration of sulfide stress corrosion cracking must be made for the corrosion resistant alloys in the same manner as for carbon or low alloy steels.
