The useful life of superheaters and reheaters of power stations which use heavy oil as fuel are shortened and their continuous service is inhibited by corrosion and creep type problems. The increase of corrosion attack of boilers is caused by the presence of fuel ash deposits containing mainly V, Na and S which form low melting point compounds. In this context, the tubes are exposed to the action of high stresses and high temperatures producing the so called “creep damage”. In this work, two kinds of results are reported: laboratory and field studies using stainless steels. The laboratory work was also divided into two parts. In the first one, the steel was exposed under the action of natural ash- deposits in oxidant atmospheres at 600QC for 24 hours. In the second one, tensile specimens were creep-tested in Na2SO4 , V205 and a mixture at 580-620QC interval. Keywords; Corrosion by deposits, reheater, power plant, creep resistance.
