What Are the Effects of Sulfuric Acid on Steel (with picture)
Feb 21 2021 · At certain concentrations sulfuric acid will form a protective layer on steel and the steel will be fine. Other concentrations will yield corrosion and the steel will slowly deteriorate. With corroding steel sulfuric acid often forms hydrogen gas which furthers the corrosion. Low levels of hydrogen gas can cause the steel to groove or warp.
