Impact between pressurized particle and surface of material will eliminate contamination immediately and cause small notch deformation. Notch indicate surface roughness value changes. Value of deformation and surface roughness changes will depend on duration of blasting to the surface, grain size, distance, and pressure of abrasive materials. Sand-lasting process usually applied after welding process on replacement of supporting component in nuclear power plant, to eliminate heat tint from the welding process that affect corrosion resistance and prevent contamination which affect component performance at extreme environment. Experiment on the AISI 304 stainless steel divided in three major steps, first was sand-blasting process on the test specimen, next step was surface roughness test, and the last one was fatigue test. Sand-blasting process was varied by grain size and blasting pressure. Grain size of glass bead materials used were Mesh 3 and Mesh 8. Blasting pressure that used were 4, 5, and 6 bar. Surface roughness test was conducted on the gage length of the specimen which referred to the standard JIS 1994 and fatigue test was done referred on standard ASTM E466. Experimental result suggested that sand-blasting process with combination grain size and blasting pressure cause changes on several surface roughness and fatigue life on AISI 304 stainless steel. Optimum surface roughness value and fatigue life would get from sand-blasting process with combination of glass bead Mesh 8 and 5 bar blasting pressure.
