The stainless steel is cold rolled, softened and descaled, similar to the process of a 2D finish. It then receives a final light pass on polished rolls known as a ‘pinch pass’. The steel remains gray in appearance, but the final pass on polished rolls produces a smoother, brighter surface than 2D finish. This is a general purpose, cold rolled finish; it is suitable for a wide range of stainless steel applications and wide range of subsequent polishing processes, such as satin finishing.
Stainless steel plate polishing is an important process for manufactures and architectural applications. Polishing stainless steel plates creates a uniform and consistent surface finish–vital for tank manufactures and OEMs supplying products to the chemical and pharmaceutical industries.polished stainless steel sheet include #4 finish and a #8 mirror finish. This section provides information on different stainless steel finishes, technical data, and best practices for ordering material.
