The influence of various parameters on crevice corrosion of two different type geometry of 304L stainless steel

الملخص EN

An investigation was carried out to study the effect of various parameters on crevice corrosion of two different type geometry of ( rod, square) 304L stainless steel in 3.4% NaCl solution under static conditions at different temperatures (25, 50) C°, rotation cylinder electrode was used for 100, 200 rpm at the same temperatures.

It was found the maximum attack was in square 304L SS at 50 C° under static conditions in account of geometric of specimen whereas slightly effect as the velocity increases due to the passive film is formed on the steel surface.

In contrast, the results show the effect of temperature changes and velocity on corrosion rate in rod 304LSS is more pronounced as temperatures and velocities rises enable the migration of chloride ions into the crevice.
