Stainless Steel No.1 Surface is a common form of primary stainless steel surface treatment in industry with the following characteristics:
Processing: made by hot rolling, annealing (high-temperature softening treatment) and pickling (removal of oxidized skin), without polishing or fine finishing.
Appearance: the surface is matte texture, slightly rough feeling, may leave a slight rolling pattern or pickling light color traces.
Uses: Mainly used for industrial equipment (tanks, pipelines), building structural parts or as raw material for deep processing (such as polishing, cold rolling).
Advantages: low cost, good corrosion resistance, suitable for scenarios that do not require high aesthetics.
Comparison: rougher than 2B surface, cheaper than BA surface (mirror), belongs to basic industrial grade material.
