Knowledge of rolling surface processing of stainless steel pipe

Knowledge of rolling surface processing of stainless steel pipe:

1. After hot rolling, annealing, pickling, and descaling, the surface of the treated stainless steel plate is a dull surface and a bit rough;

2. It is a better process than the general surface, and it is also a dull surface. After cold rolling, annealing, descaling, and finally light rolling with a rough roll;

3. This is the most commonly used in construction applications. Except for the last mild cold rolling with a polishing roller after annealing and descaling, the other processes are the same as 2D, the surface is slightly shiny, and it can be polished;

4. Bright annealing:

(a) This is a reflective surface, which is rolled by polishing rolls and finally annealed in a controlled atmosphere;

(b) Bright annealing still maintains its reflective surface and does not produce an oxide scale.
