Stainless steel rolling surface processing
Plates and strips There are three basic types of rolling surfaces that are represented by sheet and belt production processes.
No.1: After hot rolling, annealing, pickling and descaling. The treated steel surface is a dull, slightly rough surface.
No.2D: better than N0.1 surface, but also dark surface. After cold-rolled, annealed, descaling, and finally with Mao Mian roll light rolling.
No.2B: This is the most commonly used in architectural applications. Except for the last mild cold rolling with a polishing roll after annealing and descaling, the other processes are the same as 2D, and the surface is slightly glowing and can be polished.
No.2B Bright Annealing: This is a reflective surface that is rolled by a polishing roll and final annealed in a controlled atmosphere. Bright annealing still retains its reflective surface, and does not produce scale. Since the bright annealing process does not occur oxidation reaction, so no further pickling and passivation treatment.
