This study presents the results of research for micro hardness and corrosion behavior of ASTM 304 stainless steel by investigating and performing the pitting corrosion 1N H2SO4 as a function of heating temperature (500, 600, 700, 800, 900) ºC. Different amounts of carbides precipitated in the austenitic stainless steel. These precipitates are one of problems with austenitic stainless steel due to the formation of extreme pitting corrosion. The current pitting corrosion density for heated stainless steel at 900 ºC is greater than that of non-heated specimen by about 34% in 1N H2SO4. The pitting potential of heated stainless steel at 900 ºC is more negative than that of non-heated specimen by a value of 284 mV. This means that the increase in heating temperature led to the increase of pitting intensity.
