Effect of Microstructure and Heat Treatment on Resistance of Steels to Carbon Dioxide Corrosion

Resumo

The effect of the structure of steels used for making tubing strings on their resistance to carbon dioxide corrosion is studied. Special features of the influence of the shape and arrangement of the cementite component of the steels are determined. It is shown that the structural state is responsible not only for the corrosion rate but also for the susceptibility of the steels to pit carbon dioxide corrosion.
