No 1 Mill Finish Stainless Steel Plate & Sheet

Normally, stainless steel sheets are supplied in the 2B or 2D conditions.

No. 1 Finish involves rolling stainless steel that has been heated prior to rolling (hot-rolling). The steel is then heat treated, to produce a uniform micro structure (annealing). This ensures that the steel meets all necessary mechanical property requirements. After this process, the stainless steel has a dark non-uniform appearance called “scale”. Surface chromium is lost during the initial processing and heat-treating; without removal of the scale, the stainless steel would not provide the expected level of corrosion resistance. Chemical removal of this scale is called pickling or descaling, and it is the final processing step. A No. 1 finish has rough, dull, and non-uniform appearance. There may be shiny spots where surface imperfections were removed by grinding. It is generally used in industrial applications, such as equipment for elevated temperature service.
