Material 304/316L Surgical Stainless Steel

Chain Supplyy chains are made from either 304 or 316L surgical stainless steel—the same grade used in medical implants and offshore rigs. Stainless does not tarnish like silver or gold plating. It resists corrosion from water, sweat, and daily wear.

Storing Your Chain
Keep dry. Store flat or hung. Avoid prolonged contact with harsh chemicals, chlorine, or abrasive surfaces. Remove before heavy physical work or sleep if preferred.

Cleaning and Maintenance
Rinse with water and dry with the included microfiber cloth after exposure to salt, chlorine, or sweat. For deeper cleaning, use mild soap and warm water. No silver polish needed. Re-polishing service is free for Upgrade Club members.
