چکیده مقاله:

The aim of this study is to study effect of particular heat treatment on performance of 304 Stainless steel alloy which is one of the most applicable grades of austenitic stainless steel used widely in 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 lead to reduction in the average working hours in equipment in which 304 alloy is used. To remedy this problem, there are many different methods has been introduced in the recent decades. However, finding a method which increase corrosion resistance of alloy without any collapse in other 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. The results illustrated that reducing carbide participate led to better mechanical properties as well as corrosion resistance
