Stress corrosion cracking study of austenitic stainless steels by the drop evaporation test
Original language description
: The drop evaporation test (DET) is useful for study of stainless steels and related alloys resistance to stress corrosion cracking (SCC) in the chloride containing water environments at elevated temperature. This standardised test simulates the initiation of cracking under severe evaporating conditions with possibility of local chloride content increasing and precipitation (deposition) of salts and the test can be also modified. In the contribution the austenitic stainless steels (X9CrNi 19-9, X1CrNiCr 18-14-4, X2CrNiMoN 20-18-6, annealed) were compared and evaluated by the DET. The small specimens were resistively heated (?250°C) in the exposed section under dropping of diluted NaCl water solution. The initiation and short cracks growth as well as pits were observed during test. The sequence of material resistance to SCC was determined according to relations time to fracture - tensile stress and conventional threshold stresses. The subcritical transcrystalline corrosion cracks and d
