Abstract

This paper presents new data on the effect of temperature and velocity on the pitting potential E_p, corrosion potential E_corr, and pitting morphology of O, F, and T4 tempers of alloy 6013-2OSiC_p in 3.5 wt-%NaCl in the temperature range 30-130°C and at velocities of 0.5-1.0 m s^-1. The pitting potential of tempers T4 and O tended to increase with increasing temperature and flow velocity, but the pitting potential of temper F showed the opposite behaviour. Temper T4 of the alloy showed the best resistance to pitting. Alloy 6013-20SiC_p in temper T4 is therefore considered to be suitable for application in chloride containing environments.
