**Stainless Steel 904L** is a super austenitic alloy, celebrated for its rich composition of nickel, chromium, molybdenum, and copper. This unique blend offers remarkable resistance to harsh acids like sulfuric, phosphoric, and acetic acid, as well as protection against pitting and crevice corrosion in environments rich in chlorides. The electropolishing process not only elevates the surface finish by smoothing out microscopic peaks and valleys but also significantly reduces the chances of bacterial growth, contamination, or corrosion. This makes 904L electropolished pipes particularly ideal for high-purity fluid handling systems.
