Assessment of the Impact of Various Seawater Components on the Corrosion Resistance of Carbon Steels

Resumo

The resistance of steels with different carbon contents to sulfide stress corrosion cracking arising as a result of the joint effect of chlorides and sulfides contained in seawater is discussed. It is shown that corrosion cracking tests for samples under uniaxial tension at a constant strain rate can be used for accelerated testing. Parameters recommended in different regulations for assessment of steel resistance to stress corrosion cracking are compared. It is shown that the specific work of steel fracturing is an indicator reflecting most comprehensively the change in steel strength and plastic characteristics.
