Thanks, knowlittle
What i mean by pitch corrosion is that the rust on the steel is not uniform, some points are much more corroded than others.
YES, I want to blame the shipper for inadequate protection from the sea (i'm almost surre he didn't seal the doors of the cargo area).
Thanki you for the tips.
I tried the residual chlorides approach (silver nitrate test), and chlorides were detected, but the test is too sensitive (positive even for small amounts of chlorides). I would like to quantify these chlorides (don't know exactly how).
Regarding strider6 approach, how...
I would like to know if you can describe a method to prove that steel suffered corrosion when transported by sea (due to contact with seawater) instead of a normal air corrosion. The steel bars are 12 m long, and all of them are corroded (pitch corrosion)on the first 2 m,suggesting seawater...
