There are many kind of surface cooling form in the stainless steel. The most two famous method on cooling surface are 2B & BA. But how could we distinguish these two cooling rolled?

Both of them are divided into the metal surface cooling rolled, but their process are different. The steps of 2B start from cooling-rolled, hydrogen annealed and smooth on the metal cover. The annealed step are pretty different between 2B & BA. It could point out that the surface by BA much brighter than that of 2B. Actually, 2B stainless metal under pickling and annealed could be more rough and darkness on earth.

The grade/level 304 has enjoyed a large reputation in the stainless steel family. But 304J as little brother, the composition of copper per cent kind of higher than grade 304. The main usage of 304J apply for No4 and HL deepen production. Of course, 304J better thant 304 in the NI-saving area.
