The BA (Bright Annealed) finish refers to a mill manufacturing process where cold rolled stainless steel such as 2B finish is annealed in a controlled atmosphere so as to prevent oxidation and scaling..
Moreover, what are the different finishes of stainless steel?
Three more common stainless steel finishing options are:
- No. 2B – Matte finish.
- No. 4 – Brushed finish.
- No. 8 – Mirror finish.
what is 2b finish in stainless steel? 2B Surface Finish Stainless Steel 2B is a smooth, moderately reflective cold rolled finish commonly produced in the same manner as 2D, except that the final light cold rolling pass is done by using polished rolls. 2B is the most economical and widely used stainless steel finish.
Also to know, what is No 1 finish in stainless steel?
No. 1 Finish involves rolling stainless steel that has been heated prior to rolling (hot-rolling). The steel is then heat treated, to produce a uniform micro structure (annealing). This ensures that the steel meets all necessary mechanical property requirements.
How do you get satin finish off stainless steel?
Satin finishes can be obtained with metal brushing, or they can be scratched with sandpaper or other abrasive material rather than with a metal brush. A brushing technique results in a long stroke pattern. Sandblasting will provide a randomized look with no discernible pattern.
