Four low carbon steels with different Cr and Cu concentrations were prepared to investigate the effect of alloying elements on their corrosion behavior in 3.5% NaCl solution diluted hydrochloric acid and dilute sulphuric acid (pH=1.4-1.5) respectively. Electrochemical measurement and immersion test at room temperature characterized the corrosion behavior and evaluated the corrosion rate.
To investigate the role of Cr and Cu in steels in different solutions, four kinds of low carbon steel with different Cr and Cu concentrations were prepared to investigate the effect of alloying elements on their corrosion behavior. Solutions of 3.5 wt.% NaCl, diluted hydrochloric acid and diluted sulphuric acid (pH=1.4-1.5) were used.
