stainless steel staplesare made of #304, or in special cases #316, stainless steel wire. They are corrosion-resistant for extended periods of time, but not completely rust-proof in all circumstances as there is a small percentage of iron in the steel wire alloy

Applications include automotive, aviation, and marine upholstery; fencing & screening, bindery, bag sealing of all types, packaging, insulation, and virtually any application where rust or corrosion are a concern.
