What does BA in 430BA stainless steel 430BA mean? What does it mean?

430 is a stainless steel model. The content of sulfur and phosphorus in this model (which has an adverse effect on the quality of stainless steel) is relatively low.

BAfinish refers to the stainless steel with BA surface layer, the surface layer has the difference between 2B and BA, cold rolling - annealing pickling - flat 2B.

Cold rolling--bright annealing--flat BA.

The main difference is annealing, 2B is annealing, pickling, the surface is oxidized to a certain extent, and it is darker; BA is bright annealed, the surface is not oxidized, and it is brighter.

430 is a stainless steel model. The content of sulfur and phosphorus in this model (which has an adverse effect on the quality of stainless steel) is relatively low. Usually 430BA stainless steel expresses more.
