Abstract

Austenitic stainless steel 304 (AISI 304) has a good corrosion resistant, but a heat treatment process can cause a sensitization phenomenon and the corrosion resistant will decrease. One of the most serious corrosion problems that can occur is stress corrosion cracking (SCC). This study is to determine the effect of sensitization temperatures (i.e. 500 oC, 670 oC, and 840 oC) on the SCC phenomenon of AISI 304 in sulphate acid environment with total immersion method. It was observed for the specimen with sensitization temperatures of 500 oC and 670 oC, the dominant corrosion form is pitting corrosion, where the highest corrosion rate was occur on the specimen with sensitization temperature of 500 oC after 336 hours of exposure. Average of Corrosion Rate of specimen with sensitization temperatures of 500 oC, 670 oC, and 840 oC after 480 hours of exposure are 2.76 mm/y, 1.58 mm/y, and 0.9 mm/y. Stress corrosion cracking occurs on the specimen with sensitization temperature of 840 oC after 480 hours of exposure
