Stainless steel 304 pvd coating sheet has the following states, the states are different, and the dirt resistance and corrosion resistance are also different.
1. BA - excellent surface gloss, high reflectivity, like the surface of a mirror. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling;
2. 2D - slightly shiny silvery white. Processing technology: hot rolling + annealing shot peening + cold rolling + annealing and pickling;
3. 2B - silver white and better gloss and flatness than 2D surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.
