The British Corrosion Research Project – update February & March 2014

The rack contains a range of copper alloys, stainless steels, Monels, super duplex stainless , nickel alloys and titanium as well as stainless steel with special coatings.

All of the alloys are being compared with CuNi30Cr2 wrought alloy in a series of galvanic, crevice corrosion and mechanical tests specimens.

In total there are over 400 samples in three locations two in sea water and a third in a neat sewerage channel with high hydrogen sulphide levels.

At the end of the two year project the results will be a valuable guide to design engineers. It is believed that this project is a first, for so many sea water alloys being tested in one environment at the same time.
