The marking "TN316" on a ring typically refers to the material composition of the ring, specifically indicating that it is made from titanium alloy, often titanium grade 316. This alloy is known for its strength, corrosion resistance, and lightweight properties. The "TN" may signify a specific treatment or finish applied to the titanium. Overall, the marking suggests a durable and high-quality piece of jewelry.
