Corrosion is a real risk of the steel constructions because this phenomenon cause mass loss. Some kind of the corrosion is well monitorable but others are difficult to detect. Known that the heat treatment caused microstructure changement can cause ecreasing the corrosion resistance in case of unstabilized stainless steels. The reason of this problem, that the heat can cause chromium-carbide (Cr23C6) precipitation simultaneously with the reduction of the chromium content in the local grain boundaries. The chromium content ensures the corrosion resistance level. We wanted to find a relationship between the corrosion resistance and the heat treatment affected icrostructural changement.
