Abstract

A critical review of the literature has been undertaken to establish the current state of knowledge and understanding of the corrosion and stress corrosion cracking of 13 Cr martensitic stainless steels. To provide a framework for this, the service conditions oil and gas pipelines are subjected to are outlined in Section 1.
In Section 2 corrosion data for conventional, weldable and alloyed 13 Cr martensitic stainless steels are critically evaluated to establish the conditions in which the various steels are in the active state, pitting or passive state and typical corrosion rates. The impact of steel composition and environmental exposure conditions are assessed also.
In Section 3 data for hydrogen uptake and diffusivity in conventional AISI 410 steels and modified 13 Cr steels are reviewed.
In Section 4 a selected sample of the recent literature on stress corrosion cracking of the modified 13 Cr steels is evaluated, with a view to identifying the impact of different service and laboratory test variables. The main emphasis in the discussion is on establishing a clear perspective on the best approach to testing.
