PVD coating is inert and skin-safe; the real question is what lies beneath the coating. A sealed PVD layer on 316L stainless steel fully isolates the skin from the base metal.
The Truth About Nickel Allergies
Nickel allergies flare when nickel leaches to the surface. 316L steel traps nickel internally, and a complete PVD seal prevents any contact—making the combination one of the safest on the market.
When Coating Fails
Safety depends on coating integrity. A chipped or poorly applied layer can expose the base, so choose manufacturers that verify coating thickness and adhesion with real QC data.
