316L Steel: 316L surgical steel is one of the most common materials used for body piercing in the United States and is considered implant grade It is a man-made material that is made by mixing iron with other metals to achieve greater strength. The alloying process involves melting various metals together, in order to produce a “new” metal. Depending on the specific recipe used, each variety of steel gets a grade designation. It is a strong and durable metal that is very easy to clean, which is important for body piercings – especially new ones. It is also corrosion-resistant so it won’t rust or tarnish. Polishing the steel to a mirror finish results in a protective layer of chromium oxide that helps keep the nickel content trapped inside. There is a risk for people with extreme nickel allergies, in which case, titanium should be used. The number 316 has to do with the recipe of metals used when creating the steel.316L surgical steel is a very high grade of steel. The L designation means that the steel is of a “low carbon” variety, which is also very low in nickel content, making it a safe choice for people with nickel allergies. There are many different grades of surgical steel, but the only body-friendly grades are 316L and 316LVM surgical steel.
Black PVD Steel: Black PVD (Physical Vapour Deposition) involves a coating applied onto SS316L body jewellery. In order to create the black look, the jewellery is placed in a heated, high vacuum chamber, where electric voltage is applied. This process creates gases that produce ions, which are bonded to the jewellery. When the process is completed, the jewellery will have a hard layer that is both biocompatible and can be autoclaved. Black steel PVD should only be worn in fully healed piercings. The finish can come in either high polish or matte.
