Evolution of the early-stage corrosion behavior of 2 % Ni low-alloy steel in simulated marine atmosphere: Regulation by low chromium content

Key Points

• Corrosion behavior indicates that low chromium content mitigates early-stage corrosion in low-alloy steel, enhancing its durability.
• After exposure to a simulated marine atmosphere, electrochemical measurements showed a 30% increase in resistance with optimal chromium levels.
• Analysis of corrosion processes used electrochemical techniques over 60 days in controlled marine conditions to monitor changes.
• Findings suggest low chromium content management in low-alloy steel poses critical implications for structural applications, requiring further validation.
