Abstract
The paper presents methodologies and results of two case studies dealing with corrosion damage in steels. Specifically, it is concerned with corrosion fatigue and stress corrosion cracking. Description is given of preparing test specimens, special devices and loading frames that have been used to obtain significant experimental results. These are referred to influence of three different chemical solutions on the fatigue life of specimens taken from L485MB steel crude oil pipeline IKL. In the second part of the paper negative effects of stress corrosion cracking on the fracture toughness of structural steel CSN411353 were investigated and main results of this investigation are presented.
