A No. 6 Finish is a dull satin finish on stainless steel with a slightly higher reflectivity than a No. 4 Finish. It's achieved by polishing with abrasives between a No. 4 and a No. 8 (mirror) finish, often followed by a final pass with a fine abrasive or a soft buffing pad. This finish is less common than No. 4 and is typically used for specific aesthetic purposes or applications where a balance between reflectivity and texture is desired.
