Stainless steel is one of solution for corrosion problem that usually happen in industrial environment because of its corrosion damage resistance, but in some case stainless steel are not resist to corrosion especially stress corrosion cracking (SCC). The phenomenon of SCC has been observed by many scientist not only in morphology <br /> <br /> <br /> <br /> <br /> and mechanism aspect but also effect of its paramaters that consist stress, temperature and concentration of environment. SCC is one of damage that not only caused by corrosion reaction but also stress effect. Failure caused by SCC usually occured suddenly and unexpectedly eventhough the remaining life is not over yet. Hence, SCC damaging phenomenon in metal especially stainless steel became serious concern not only to avoid material or financial loss but also accident. <br /> <br /> <br /> <br /> <br /> This research have goals to observed damage caused by SCC based on morphology and contour analysis especially for 304 and 316L stainless steel where the variables that was used are percent strain and temperature. This research is <br /> <br /> <br /> <br /> <br /> according immersion corrosion testing method for approximately 5 days long at 25oC and 60oC. The result that will be obtained from this testing is microstructure that <br /> <br /> <br /> <br /> <br /> show condition of cross-section from the specimen. Research resulted that there is no crack in 304 but in 316L that is have more corrosion resistance it shows crack. From crack depth measurement in 316L, the result show at temperature 25oC for percent strain 20% the crack depth is 130,19 &#956;m for percent strain 30% the crack depth is 254,82 &#956;m, on the other hand the result at temperature 60oC show for percent strain 20% the crack depth is 2545,6 &#956;m and for percent strain 30% the crack depth is 3000 &#956;m, it indicate that increasing temperature show more significant effect that <br /> <br /> <br /> <br /> <br /> increasing percent strain.
