Black steel is 316L surgical stainless steel that has been given a scratch resistant black coating using a PVD (Physical Vapour Distribution) process. Surgical steel is a stainless steel with the 316L designation. Just like any other steel, this steel contains nickel. However, the nickel release rate for 316L surgical stainless steel is well below the allowable value given in the EU nickel directive, which makes it hypoallergenic and well suited to use in piercing studs and fashion earrings.
