TP032 - The Effect of Microstructure on Pitting Resistance of Super Duplex Stainless Steels

This paper develops a novel technique for studying the pitting behaviour of alloys in saltwater, with Ferralium^® used as the benchmark alloy.

It also considers how the microstructure can be controlled to optimise the critical pitting temperature.
