This is how electropolishing affects the corrosion protection of austenitic stainless steel. Studies conducted reveal that electropolishing is an effective process in enhancing the corrosion resistance of steel within the 316L group. According to these studies, the corrosion rate decreases by 58–78 percent, and the resistance to pitting corrosion improves by 85–91 percent.
The crucial chromium/iron ratio, significant for corrosion resistance, increases after electropolishing, and the passive layer formed during electropolishing is 50–120 percent thicker than the one naturally formed on 316L when exposed to air.
