Resists CO₂ pitting
Ni occupies vacancies to block corrosive species and Mo promotes Cr enrichment and rapid repassivation, markedly suppressing localized corrosion.

Exposed to CO₂-saturated NaCl solutions at 90 and 180 °C for 6–168 h
Ni and Mo alloying reduces general corrosion rates at early stages
Long-term general corrosion rates controlled by FeCO₃ crystals rather than inner Cr-enrichment films
Localized corrosion markedly retarded
