Stress Corrosion Behaviors of Three Typical Materials (304L, 2205, Alloy 825) in Boiling Magnesium Chloride Solution

According to YB/T 5362-2006 “stainless steel stress corrosion test method in boiling magnesium chloride solution”, the sensitivity of the stress corrosion of three typical materials (304L, 2205, Alloy 825) was investigated in boiling magnesium chloride solution (experimental temperature is 143±1 °C, concentration of magnesium chloride is 43%). The results show that under the condition of constant strain, the corrosion resistant performance of 825 material is far better than 304L, and the corrosion resistance of dual phase steel may not be superior than that of austenitic stainless steel.
