BA surface: cold rolling → bright annealing → smooth.
2B surface: cold rolling → annealing and pickling → smoothing.
For the same steel type, what is the difference between the BA surface and the 2B surface after grinding?
There is basically no difference between the 2B surface and the BA surface after grinding. They differ mainly in the time and cost of the grinding process. The surface of 2B wears for a long time and the cost is high; the surface of BA is less expensive because of its bright surface.
Generally speaking, BA plate just refers to a stainless steel cold-rolled plate with a certain surface state, and its applicable scope is also very wide, such as: kitchen utensils, building materials, decoration, automobile and other industries. In terms of polishing, the BA surface has more advantages than the 2B surface, and it looks more beautiful and smoother.
