AISI SUS DIN 301 304 HIGH PRECISION STAINLESS STEEL STRIPS

No. 3 Finish – This finish is obtained with a ground unidirectional 80 to 100–grit abrasive. It is sometimes an intermediate step for finer finishes.
No. 4 Finish – This finish is obtained with a ground 150-grit abrasive.
No. 43 Finish – Appliance finish
Many other finishes can be applied to stainless steel as well. Contact us for technical expertise in selecting the right one for you. Choosing the right finish can be critical for many applications.
No. 2D - A smooth, non-reflective cold-rolled annealed and pickled or descaled finish.

No. 2B - A smooth, moderately reflective cold-rolled annealed and pickled or descaled finish typically produced by imparting a final light cold-rolled pass using [large diameter] polished rolls.

Bright Annealed [BA] Finish- A smooth, bright, reflective finish typically produced by cold rolling followed by annealing in a protective atmosphere so as to prevent oxidation and scaling during annealing.

No. 3 Finish is characterized by short, coarse, parallel polishing lines, which extend uniformly along the length of the coil.

No.4 Finish is characterized by short, parallel polishing lines, which extend uniformly along the length of the coil. It is obtained by mechanically polishing a No. 3 finish with gradually finer abrasives.

No.7 Finish has a high degree of reflectivity and a mirror-like appearance. A No. 4 finish that has been polished to 320-grit is buffed for up to 10 minutes but existing grit lines are not removed. The remnants of fine polishing lines can generally seen by an observer standing several feet from a panel.

No.8 Finish It is produced in the same manner as the No. 7 finish except that the buffing is continued for an additional five to ten minutes. In comparison to a No. 7 finish, the grit lines are much less visible, but they can be seen if the finish is examined closely. The resulting finish is mirror-like but not a perfect mirror.
