CORROSION BEHAVIOUR OF AUSTENITIC STAINLESS STEEL GRADE 316 IN STRONG ACID SOLUTION

The resistance and susceptibility of austenitic stainless steel grade 316 exposed to strong acids solution (1M H2SO4, 4M H2SO4 and 1M HCl) at ambient temperature. Weight loss method was used to examine the corrosion rate of steel after immersion in the corrosive media or environment. During the research work reports observed severe general and pitting corrosion and the resistance of the steel to corrosion at different corrosive environment (concentration of the acid media). The result obtained showed the weak corrosion resistance / appreciable corrosion susceptibility of the austenitic stainless steel grade 316 to the test environment.
