What is stainless steel AB board, please?
The BA board is not used for drawing purposes, if it is drawing, put fine timber to petty use is wasted.
It should be said that BA (Bright, Annealing, bright annealing) plate, and 2B plate difference is that annealing process is different, 2B using annealing and pickling combination process, BA using hydrogen protection, annealing under anaerobic environment. The rolling process and leveling process of the two surfaces are also different.
The 2B board is basically a matt surface, according to a BA object, in approximate mirror, can more clearly illuminate the object (a little paste).
Both 2B and BA can be polished into 8K mirror panels, but 2B requires more polishing steps, and the BA can only be polished to achieve the 8K effect. Depending on the end product, there is a difference in whether the BA is polished and some BA products do not need to be polished and used directly.
