Abstract

The fatigue response of selected high strength low alloy steels, that are under consideration for future offshore structural applications, was investigated. Freely corroding and cathodically polarized experiments were conducted under conditions relevant .to these applications. Cathodic polarization experiments involved testing of A537 Direct Quenched (A537 DQ) steel at different potentials in the -0.80 V to -1.10 V (SCE) range. The damage to freely corroding high strength steel was more than on structural steel for calculations based on the Wirsching wide band spectrum. Polarization to -0.80 V (SCE) improved the fatigue life of A537 DQ steel over the freely corroding life. A definite conclusion with regard to the influence of different levels of cathodic polarization on the fatigue life of the steel investigated can not not be drawn based on the results from this study due to data variability.
