304 Stainless Steel Jewelry. The most common type of stainless steel in jewelry and in other industries, this type is known for its versatility, affordability, and its strength, possessing many of the usual qualities stainless steel would commonly have. 304 stainless steel is suitable in most environments, with the exception of places that have high chloride levels, as these may put your jewelry at risk for corrosion and cracking. Lifestyles that include dealing with chloride solutions or even frequent trips to the beach will definitely lessen the lifespan of your jewelry, so you may want to consider not wearing your jewelry to these places entirely, or simply consider getting a different type of stainless steel!
316L Stainless Steel Jewelry. Another common type of stainless steel, the 316 is used mostly as surgical equipment and marine parts for its higher corrosion resistance--especially against chlorides. Considering its usage in the medical field, 316L stainless steel jewelry is by far the most body-friendly material. The presence of molybdenum in its chemical compound make it a better, more durable version of the 304, and its higher resistance to corrosion makes it perfect for people who enjoy long walks at the beach!
904L Stainless Steel Jewelry. Possibly the highest quality of stainless steel among the three, the 904L is the type that is used not only in marine operations as a higher grade material than the 316L Stainless Steel Jewelry, but is also used by the luxury watch manufacturers Rolex and OMEGA. Compared to the other two types, the 904L contains the highest amount of chromium, molybdenum, nickel and copper, enhancing its already strong characteristics to an alloy that is even more durable and corrosion resistant to all elements. 904L stainless steel offers highest quality durability along with a shiny finish, fitting for those who enjoy a little extra sparkle in their day to day life.
