The high-temperature corrosion behavior of four valve steels\n(X33CrNiMn23-8, X50CrMnNiNbN21-9, X53CrMnNiN20-8 and X55CrMnNiN20-\n8) in combustion gases of fuel oil, containing different concentrations of bio-components\n(5 and 10 wt%) has been studied under thermal shock conditions. It was found\nthat the addition of bio-components decreased the corrosion resistance of steels\ninvestigated. It was also found that the X33CrNiMn23-8 steel containing the highest\nchromium concentration, behaved in the investigated atmospheres much better than\nthree remaining steels due to the formation of highly protective chromia scale.
