The paper studies the corrosion resistance of 40Cr130 in different structural states. The material is thus characterized in the annealed, normalized, quenched, tempered state and, respectively, following a thermochemical treatment.

Good corrosion resistance was found in all states, and substantial improvements were noted following the thermochemical nitriding treatment.
