No 2 Mill Finish Stainless Steel Plate & Sheet

No. 2D Finish is a uniform, dull silver gray finish . It is applied to thinner coils whose thickness has been reduced by cold rolling. After rolling, the coil is then heat treated to produce a uniform microstructure (annealing), which enables it to meet the necessary mechanical property requirements. After  the heat treatment,  pickling/descaling is required to remove the dark surface layer (due to chromium depletion) and restore corrosion resistance. Pickling can be the final step in production of this finish, if finish uniformity and/or flatness are unimportant. However, if a specified finish is required, there is a final step, which involves light cold rolling pass through dull rolls. A No 2D finish  retains lubricants well, making it the preferred finish for deep drawing components. It is often used as a substrate, as this finish offers excellent paint adherence.
