For body jewellery three steels are used - Composition D Implantation Steel, 316L surgical steel and 316LVM Surgical Steel. Although these high grades all contain nickel, they do not release nickel salts into the body and do not induce contact nickel dermatitis. All steels meet the annex criteria in the EU Nickel directive and can be used indefinitely worldwide for secondary piercing applications.
Surgical Stainless Steels are used for body jewellery and manufactured from equivalent or higher standard material. Many of steel body jewellery items have been electro polished, which is a sophisticated surface finishing technique, where electrochemical activity slowly erodes a thin layer from the surface of the jewellery resulting in micro smoothing. The resultant surface is ultra smooth and crevice free. It has a higher surface integrity and efficiency than jewellery polished by other means.
