Reliability of materials of construction is becoming of ever increasing importance particularly on offshore platforms where replacement costs are prohibitively expensive. A new generation of stainless steels in both austenitic and duplex grades are now available which offer substantial improvements on the more conventional AISI 300 series. The mechanical and physical properties of these materials, with particular reference to pitting and crevice corrosion will be outlined.

Nickel aluminium bronze has been a traditional material of construction for many years but its variable corrosion characteristics has led to the introduction of more resistant chromium containing cupro-nickels.

In the ultimate instance where no corrosion can be tolerated then the choice is between titanium and its alloys and the high nickel alloys particularly Inconel 625 and Hastelloy C.

The influence of high velocities and stagnant conditions on materials' performance will be covered together with the effects of chlorination on the pitting characteristics of sea water
