Stainless Steel Polished Tube
During the production of stainless steel tubes, the surface of the alloy may have some irregular particles that stick out. The presence of any irregularities on the surface of the metal may cause the alloy to get corroded. To improve the finish of the surface, the tube is polished. With the finishing on the surface of the stainless steel polished tube (polished stainless steel square tubing), the irregularities are eliminated by mechanical processes.
The abrasives used in the polishing of Polished Stainless Steel Tube 25mm includes equipment in the form of wheels, belts, as well as abrasive media. It is possible to achieve a reflective surface on the tube by means of polishing. The subsequent polishing practiced on the surface, yields a Stainless Steel Mirror Tube. The finer abrasives and buffing at an extensive rate eliminates all the grit lines that were carried over from preliminary grinding operations. While polishing is a cosmetic kind of finish that is a practice to obtain Stainless Steel Tube Mirror Finish. In comparison to other polishing processes, the one used to produce a mirror effect is known to be of a higher quality.
While the goal of a Stainless Steel Electropolished Pipe is to achieve a reflective surface, Mirror quality steel is classified as 6K and above, depending on the mirror effect achieved. For instance, Polished Stainless Steel Square Tubing is classified into three types - 6K, 8K, and 10K. The classification carried out on the Stainless Steel Round Tube Polished will depend on the degree of its mirror effect once the tube has been processed.
