This is not so in water: there, corrosion as function of temperature shows a marked maximum around 250" C for AISI 410 steel. For AISI 304 steel the maximum, which was not actually observed, must lie at a lower temperature.Chloride Stress Corrosion Cracking SSINAThe resistance of austenitic stainless steels to SCC is related to the nickel content of the steel. The most susceptible austenitic grades have nickel contents in the range of 8 to 10 wt%. Therefore, standard grades such as 304/304L and 316/316L are very susceptible to this mode of attack.
