Appraisal about Stainless Steels for Piercing Jewelry

Abstract

This paper introduced several conventional stainless steels for piercing jewelry, and discussed their corrosion resistance, nickel allergy problem and risk of piercing infection. The authors proposed that several requirements should be taken into consideration in developing stainless steel materials for piercing jewelry, including corrosion resistance, safety, anti-bacterial, castability, workability, weldability, surface treatment property, and etc. High nitrogen and nickel free or low nickel stainless steels with anti-bacterial performance, which had many unique characteristics such as excellent corrosion resistance, no nickel allergy and less risk of piercing infection, would become a new development trend of stainless steels for piercing jewelry.
