No. 2D - A smooth, non-reflective cold-rolled annealed and pickled or descaled finish.
- 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.
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
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.
Stainless steel sheets are perfect for:
Food handling and processing – surfaces and surrounds, such as counters and splashbacks
Dairy processing plants and milking equipment
Kitchen appliances and some cookware
Hospital equipment and surfaces
Kickplates for doors
Other applications in which the strength of steel is required as well as resistance to corrosion
Despite the name, Stainless Steel can stain slightly over time, in particular (extreme) conditions. These include low-oxygen environments, and those in which there is a high level of salinity (such as constant exposure to seawater). This can be mitigated by regular cleaning and maintenance, and the alloy is significantly more resistant to damage in these conditions than other alternatives. However, in the vast majority of circumstances corrosion and staining should not be an issue. The Chromium content of the steel forms a light oxide film on the surface which prevents further oxidation in all but the harshest environments. This prevents corrosion from spreading to the inside of the sheet.
