The redox potential of some etching reagents and the corrosion potential of various stainless steels and alloys were measured and the etching behavior of γ, α and σ phase in stainless steel were explained electrochemically. The results obtained were as follows: (a) In acid reagents, low-chromium ferritic and austenitic stainless steels are corroded but high chromium alloys fell into the passive state. For this reason when stainless steel containing σ phase is etched in acid reagents, γ or α phase are corroded and σ phase, higher in chromium than α or γ phase, is not corroded. (b) On the other hand, in alkaline reagents, low-chromium austenitic stainless steels are not corroded but high-chromium stainless steels and alloys are corroded and stained. For this reason, when stainless steel containing σ phase is etched in the alkaline reagents, γ phase is not corroded and α or σ phase are corroded and stained.
