What is 316L Surgical Stainless Steel? — Why This Medical-Grade Material is Chosen for Jewelry
"Aren't stainless steel accessories cheap-looking?" Many people have probably thought this. However, the 316L surgical stainless steel adopted by BLACK CLAW is completely different from ordinary stainless steel. It is the highest-grade material, also used in medical scalpels and artificial joints.
Differences between 316L and ordinary stainless steel
Compared to ordinary stainless steel (such as SUS304) used in daily necessities and construction, 316L has molybdenum added. This significantly improves its corrosion resistance, and its greatest feature is that it is highly resistant to discoloration and degradation even when exposed to seawater or sweat for long periods.
The "L" stands for Low Carbon. By suppressing the carbon content, it prevents intergranular corrosion during welding and further enhances the material's stability.
Why it's strong against metal allergies
The main cause of metal allergies is nickel ions that dissolve and react with sweat and body fluids. Although 316L surgical stainless steel contains nickel, its special crystal structure results in extremely low elution, giving it biocompatibility suitable for medical implants.
This is a material that we particularly want those who "gave up on accessories because of metal allergies" to try.
In the unlikely event of an allergic reaction after wearing, returns will be accepted within 14 days of wearing.
OK to wear 24/7
The durability of 316L handles all daily situations.
- Sea/Pool — Strong against saltwater and chlorine, no discoloration
- Sauna/Bath — No degradation even in high temperatures and humidity
- Weight Training/Sports — Strong against sweat, resistant to scratches
- Work/Business — Elegant luster lasts a long time
No need to take it off, so it becomes a part of your lifestyle. That's the true value of 316L accessories.
Differences from Silver (S925)
S925 sterling silver is attractive for its unique texture that deepens with age. However, it reacts with hydrogen sulfide in the air and tarnishes, requiring regular maintenance.
316L surgical stainless steel is maintenance-free. For those who "don't have time for maintenance" or "hate bothersome things," 316L is the optimal solution.
| Item | 316L Stainless Steel | S925 Silver |
|---|---|---|
| Discoloration | Almost none | Yes (tarnishing) |
| Maintenance | Almost unnecessary | Polish regularly |
| Water Resistance | Sea/Sauna OK | Avoid water |
| Allergy | Unlikely to occur | Unlikely to occur |
| Aging | Unchanging beauty | Develops character |
Why BLACK CLAW chooses 316L
BLACK CLAW's concept is "accessories you never take off, 24 hours a day, 365 days a year." In the gym, at the beach, in business, on a date. To accompany you in all scenes of your life, 316L surgical stainless steel was a natural choice of material.
Its substantial appearance is comparable to silver, its price is accessible, and above all, it offers the ultimate comfort of "being able to forget you're wearing it." That is BLACK CLAW's 316L accessory.
