Stainless steel surface processing grade:

Raw surface: NO.1 surface subjected to heat treatment and pickling after hot rolling.

Generally used for cold rolling materials, industrial tank tanks, chemical industrial equipment, etc., the thickness is from 2.0mm to 8.0mm.

Blunt surface: NO.2D cold rolled after heat treatment, pickling, its material is soft, the surface is silver-white luster, used for deep stamping processing, such as automobile components, water pipes, etc.

Fog surface: no.2b after cold rolling, heat treatment, pickling, and fine rolling to make the surface a moderate brightness.

Because the surface is smooth, easy to regrind, make the surface more bright, use extensively, such as tableware, building materials.

The surface treatment with improved mechanical properties satisfies almost all USES.
