Stress corrosion cracking of 304L stainless steel in molten salts media

A tensile apparatus with constant strain rate, suitable for corrosion tests in molten salts has been used to determine the mechanical characteristics of 304L stainless steel in molten NaClCaCl₂ at 570°C fromα= f [(Δl)/(l₀) %]curves for different strain rates. Potentiometric measurements, executed simultaneously, have determined the electrochemical conditions during mechanical testing. Results show a strain rate field in which the stress corrosion cracking occurs.
