316L Cold Rolled Stainless Steel Sheet No.4 Finish 0.4mm-8.0mm Satin Surface Marine Grade
316L cold rolled stainless steel sheet with No.4 finish combines the superior corrosion resistance of molybdenum-bearing 316L with a uniform satin surface that hides fingerprints and scratches. The No.4 finish is produced by mechanical polishing with progressively finer abrasives.
This combination makes the sheet the first choice for marine, food processing and architectural applications where both appearance and corrosion performance matter.
