The aim of this study is to study the effect of particular heat treatment on the performance of 304 Stainless steel alloy which is one of the most applicable grades of austenitic stainless steel used the wide storage tank to chemical transportation. Although this alloy has suitable properties for engineering uses, its poor resistance to intergranular corrosion restricted its use in industries. Meanwhile, this problem leads to a reduction in the average working hours in equipment in which 304 alloys are used. Methodology: To remedy this problem, there are many different methods has been introduced in the recent alloy’s properties still a challenge. In this study, different heat treatment cycles on the 304 alloy were applied and then the corrosion rate was measured. Furthermore, mechanical tests were carried out to find out which cycle resulted in optimum properties. Results: The results illustrated that reducing carbide participate led to better mechanical properties as well as corrosion resistance. Conclusion: According to test results, stainless steel grade 304 corrosion properties improved by solution annealing heat treatment, but this improvement stopped after a specific time. Furthermore, for this grade of steel with 2-millimeter thickness, the best heat treatment time is about 20 to 25 minutes in 1100ºC.References
