Deposition of 304 or 316 stainless steel metal ions
Thread Content
I would like to ask whether metal ions will precipitate from 304 or 316 stainless steel in normal temperature water solutions Will metal ions precipitate in an acidic (pH 4.5–6) aqueous solution at 100°C? Product refinement involves filtration equipment made of stainless steel, and high standards are required regarding metal ions in the product.
304 or 316 stainless steel should not release metal ions into normal temperature water solutions. Metal ions may precipitate in an acidic (pH 4.5–6) aqueous solution at 100°C, depending on the type of acid used.
The possibility of precipitation is very low; this is something that can be tested, and an analysis can be conducted after the testing
