316L indicates stainless steel. It is the most basic metal manufacturers use for body jewelry. Although it is not a precious metal, it is more durable than silver or platinum. It is because of its chromium coating that chemically bonds to the steel. This coating protects the steel from tarnishing and rusting. The chromium coating also protects your item from scratches by taking the initial impact. It is the spontaneous formation of a hard non-reactive surface film that prevents corrosion. Many believe that stainless steel is better than silver, gold, and titanium, although it is cheaper. But the only reason it is cheaper is that it is more abundant than other precious metals. Stainless steel is an excellent jewelry material because it is durable and affordable. It will not corrode, rust, stain, tarnish, fade, or turn your skin green. But you need to make sure that the jewelry you buy uses high-quality 316L surgical grade stainless steel. Care tips for your stainless steel jewelry: Wash it with bacterial soap and warm water before use. Do not use alcohol or harsh chemicals to clean it if your steel jewelry has acrylic or gems.
