AbstractIn this study; The effect of the solution and aging heat treatments on the corrosion behavior on high chromium cast steel samples with the compositon of 1.61% C + 25% Cr + 0.74% Si + 0.55% Mn + 0.38% Mo + 0,23% Ni + 0.15% V were investigated. The samples solution heat treatment - rapid cooled for 4 hours at 1150 ℃, aged for different times between 5-25 and in cast (original) status were subjected to corrosion treatment. Corrosion behavior was investigated by immersion method in 10% FeCl3 and 10% H2SO4 medium. As a consequence, the least corrosion rate was seen on the sample kept at the solution condition and then cooled by water rapidly while higher corrosion rates were observed on cast (original) status and aged samples.
