| Abstract | The detrimental effect of cold working on pitting corrosion resistance was surprisingly found totally eliminated in high nitrogen stainless steels (HNS) with higher nitrogen content (0.92 wt.%) by electrochemical tests in chloride solution. Inclusions morphology and microstructure of cold-worked HNS were investigated. Then the passive film on HNS was analyzed by secondary ion mass spectroscopy (SIMS). For the first time nitrogen enrichment as a form of short range ordered [CrN] was observed in the chromium oxide layer of passive film on HNS. A possible reaction involving nitrogen enrichment is proposed to elucidate this exceptional behavior of corrosion resistance for HNS.; The detrimental effect of cold working on pitting corrosion resistance was surprisingly found totally eliminated in high nitrogen stainless steels (HNS) with higher nitrogen content (0.92 wt.%) by electrochemical tests in chloride solution.
