Long-term storage of metal alloys can lead to corrosion, cracking, embrittlement and subsequent destruction. The main factors that determine the rate of corrosion in the atmosphere are the relative humidity, temperature and its changes, the presence of contamination, the presence of chlorides, oxides of sulfur and carbon, hydrogen sulfide, etc. The storage conditions were modeling at the temperature and temperature/humidity test chamber, which allows creating certain climatic conditions for a selected period, approximating to storage conditions. Using the Versa Princeton Applied Research potentiostat electrochemical measurements have been made to compare the corrosion resistance of the alloys to rank the materials in terms of corrosion resistance. It was revealed that 10Cr11Ni23Ti3MoB steel is the most corrosion-resistant material of this study, and it is correlate with the test-chamber results. 30CrMo steel is not recommended for long-term storage in humid conditions, where condensation or direct contact with water is possible on its surface.
