In my shop all stainless steel interchangeable jewelry parts are made of stainless steel AISI 304 or AISI 316.

All stainless steel has a nickel, but it is important how many of nickel will be released in the derma-contact. A study of nickel release and allergic contact dermatitis from nickel-plated metals and stainless steels was published in more journals. It was shown that low-sulfur stainless steel grades like 304, 316  release less than 0.03 microgram/cm2/week of nickel in acid artificial sweat and elicit no reactions in patients already sensitized to nickel.
