The 316L has less nickel in it and is far brighter in appearance and tends to stay that way. Nickel can be an irritant to some. The 904L is often used for body jewelry or piercings and it is not particularly expensive.

Another cool thing about titanium is that it is hypo-allergenic, whereas stainless steel can cause allergies in some people due to the 8-10% nickel content in the alloy. Rolex watches are even more susceptible to allergies because of their 904L steel having almost twice as much nickel as the common 316L. Again, titanium is a non-issue.

CATLOGIXJewellery in stainless steel is commonly made from 316l or 316lvm and is often called medical grade stainless steel as it doesn't react to the skin.well, for most people. 316 does contain around 12% nickel but meets EU directives on nickel leaching, however it can still cause a reaction for some people with a sensitive nickel allergy.
