Short summary
Compressive deformation up to 20% enhances the corrosion resistance of 00Cr30Mo2 ferritic stainless steel by promoting protective Cr2O3 formation, while higher strains degrade performance due to excessive defects.

Key points
- Corrosion resistance of 00Cr30Mo2 ferritic stainless steel initially increases then decreases with compressive deformation.
- Optimal corrosion resistance is observed at 20% compressive deformation.
- The optimal level promotes the formation of a protective Cr2O3 layer.
- Excessive defects formed at higher deformation levels degrade corrosion resistance.

Abstract
Prior strain significantly affects the corrosion resistance of stainless steels. This study examined the influence of compressive deformation on the microstructure evolution and corrosion behaviors of 00Cr30Mo2 ferritic stainless steel. Results indicated that corrosion resistance initially increased and then decreased with increasing deformation, reaching optimal levels at 20% compressive deformation. Appropriate deformation level (20%) promoted the formation of Cr 2 O 3 . However, further deformation led to excessive defects that degraded corrosion resistance.
