The susceptibility to stress corrosion cracking of carbon and two low alloy steels of different strength was determined in seawater at corrosion and cathodic potentials with the Slow Strain Rate Tensile Test. The slight decrease in time to-failure, fracture energy and reduction-in-area at corrosion potential and substantial decrease in those parameters at application of cathodic polarisation in comparison with the values measured in air, were observed. The significant linear relationships between the degree of degradation and the eon tent of diffusive hydrogen were obtained for investigated steels. Within the potential range existing on the ship hull at its cathodic protection, no important difference in the lass in mechanical properties was stated between tested steels, despite their different strength.
