- Description
- This paper considers the combined effect of water temperature and the carbon content of low alloys steels on their immersion corrosion loss. Experimental results for exposures over 1.75 years are reported for low alloy steels with carbon contents of 0.01%wt, 0.04 %wt and 0.06 %wt, recovered at intervals of about 4 weeks. One set of each of these three types of steel coupons was in a tank with periodic renewal of natural coastal seawater and another immersed in a tank with seawater from the same source but heated to a constant 30°C. In both tanks the water was changed slowly, taking about 5 minutes to replace the 200L in each of the respective drums, at 12 hour intervals. The water in that tank was preheated to avoid sudden temperature changes. In both cases the water was essentially stagnant throughout the experiment. For the first four months the 0.01% C corroded slightly more than the 0.04%C which was in turn slightly higher than the 0.06% C. In all cases, there was a bimodal trend in the corrosion mass loss. There was a clear difference in corrosion mass loss as a function of water temperature but this was greater for the longer exposures. A slight difference in corrosion loss was observed between the steels with different carbon contents.
