Stainless steel plate 304 2b board and ba board What is the difference:
Cold rolling - annealing pickling - leveling 2B
Cold rolling - bright annealing - leveling BA
2B ordinary cold-rolled surface of stainless steel table surface (non-drawing of the kind)
BA ordinary mirror drum washing machine inner tube surface
The main difference is the annealing, 2B is the annealing, pickling, the surface has a certain degree of oxidation, darker; BA bright annealing, the surface is not oxidized, brighter.
304 stainless steel
2B board: no glossy
BA board: a little bright ordinary mirror
Stainless steel and mirror, that is, 8K board, like a mirror
BA 2B process is not the same, the finished product is not the same.
BA plate with a roughness of 0.006-0.008 work roll rolling, and vertical furnace annealing, the surface is like a mirror;
2B side Miao with roughness of 0.2-0.28 work roll rolled from the general use of horizontal back to the production, the surface is rough.
