Effects of Temperature and Humidity on Atmospheric Stress Corrosion Cracking of 304 Stainless Steel
Austenitic stainless steels(SS) are widely used as structural materials of chemical and power plants. External stress corrosion cracking(ESCC) by sea salt particles were observed in the structural materials of these plants. ESCC susceptibility depends on the environmental factors. The effects of temperature and relative humidity on ESCC of type 304SS were studied experimentally in this paper. Uniaxially tensile loaded specimens were used for the ESCC test. The tensile loaded specimens were kept in a constant temperature and humidity chamber after dropping artificial sea water on the gage section. Crack length and depth were measured and used to evaluate ESCC susceptibility. The ESCC growth rate was examined from the view points of the temperature and the relative humidity dependency, and of the activation energy.
