316L stainless ist absolutely nickel-free, as far as i know.
Its true, there are types of steel, containing nickel, but not in 316L.

"The second most common austenite steel is the 316 grade, also referred to as A4 stainless and called marine grade stainless, used primarily for its increased resistance to corrosion. A typical composition of 18% chromium and 10% nickel, commonly known as 18/10 stainless, is often used in cutlery and high-quality cookware. 18/0 is also available."
