The paper shows the results obtained under chlorination conditions on low alloyed steels 15HM (T/P12), 16M (T/P1), 18K, and 10HM2 (T22) in temperature range 450–550 °C for 100 h. tests were performed a gas mixture of 0.3 % Cl2–Ar 1 bar pressure. indicated that underwent high degree corrosion, showing lack protection reducing atmosphere. However, some differences regarding chemical composition bare found. scale thicknesses, compositions chloride scales developed exposed samples analysed by means standard techniques including scanning electron microscope coupled with energy X-ray dispersive spectroscopy.
