Sulphuric acid stainless steel
Web12 Aug 2024 · Acid staining: Any liquid with a pH less than 1.0 can stain stainless steel. A liquid with such a low pH is an acid that is too strong for common use, but certain sulfuric acid-based drain cleaners may qualify. Avoid putting them in the sink. Advertisement Some stains are caused by a combination of chemicals. Image Credit: Nature's Nurture WebHow Stainless Steel Pickling Works. Pickling is a pre-passivation process of treating stainless steel parts with an acid solution, typically hydrochloric or sulfuric acid, which can remove oxide scale and heat tint while dissolving steel flecks embedded in the part. But pickling is a very imprecise process, with many drawbacks, including strict ...
