Abstract

The corrosion resistance of three grades of valve steels (X33CrNiMn23-8, X50CrMnNiNbN21-9, X53CrMnNiN20-8) in combustion gases of propane-butane (LPG) under thermal shock conditions has been studied. It was stated that X33CrNiMn23-8 steel, containing highest concentration of chromium and nickel and also the lowest of manganese concentration, showed the best corrosion resistance in comparison to another tested steels. The worse corrosion resistance in combustion gases of propane-butane (LPG) was stated in reference to X50CrMnNiNbN21-9 and X53CrMnNiN20-8 valve steels containing lower chromium and nickel concentrations.

Keywords: Valve steels, corrosion resistance, thermal shocks, combustion gases of LPG
