Rough matte surface is rolled to specified thickness, then annealed and descaled
No glossy surface is required for use
NO.2D(silver)
A matt finish, cold rolling followed by heat treatment and pickling, sometimes with final light rolling on wool rolls
2D products are used for applications with less stringent surface requirements, general materials, deep-drawing materials
NO.2B
