This research was carried out by first testing using the Spring Loaded Fixture type in accordance with ASTM G49 and E 292 for the experimental method and specimen geometry respectively. Initiation of SCC failure begins with pitting corrosion and thinning attacks to date stress reaches the highest strength Furthermore, in this case the aim was to determine the characteristics of failure of SCC Austenitic stainless steel AISI 304, AISI 316, and 316L in Glycerol solution with four variations of chloride concentration, namely 50, 6,000, 9,000, and 12,000 ppm, two types of initial tensile stress, namely 50 % and 70% Yield Strength from each material test, and 150 oC constant temperature.Failure occurs in catastrophic and brittle (transgranular) fractures. AISI 304 is more vulnerable to all experimental conditions. All material tests did not fail for 50 ppm chloride concentration up to 556 hours of exposure time. The more concentration and chloride concentration is given, the crack speed becomes higher by shortening the failure time.
