Not All Stainless Steel is Created Equal
When it comes to hypoallergenic jewelry, the type of stainless steel matters just as much as the design. At ATLASECA, we exclusively use 316L and 304 stainless steel for our collections—and there's a very good reason why.
Understanding Stainless Steel Grades
Stainless steel comes in many different grades, each with unique properties. The numbers refer to the specific composition of metals in the alloy. While there are hundreds of grades, only a select few are suitable for body-safe, long-lasting jewelry.
304 Stainless Steel: The Foundation of Quality
304 stainless steel, also known as 18/8 stainless steel, contains 18% chromium and 8% nickel. This grade is:
- Highly corrosion-resistant: Perfect for everyday wear, even in humid conditions
- Durable and strong: Maintains its shape and structure over time
- Hypoallergenic: Safe for most people with sensitive skin
- Easy to maintain: Resists staining and requires minimal care
304 stainless steel is commonly used in medical instruments and food-grade applications, which speaks to its safety and reliability.
316L Stainless Steel: The Premium Choice
316L stainless steel takes quality one step further. The "L" stands for "low carbon," and this grade includes molybdenum (2-3%), making it even more resistant to corrosion than 304.
Why 316L is exceptional for jewelry:
- Superior corrosion resistance: Withstands exposure to saltwater, chlorine, and harsh environments
- Surgical-grade quality: Used in medical implants and body piercings
- Ultra-hypoallergenic: The lowest nickel release of any stainless steel grade
- Exceptional durability: Resists pitting and crevice corrosion
- Biocompatible: Safe for prolonged skin contact
316L is the gold standard for people with metal sensitivities and nickel allergies.
Why ATLASECA Uses Only 316L and 304
We're committed to creating jewelry that you can wear every single day without worry. Here's why we exclusively use these premium grades:
1. Skin Safety First
Both 304 and 316L stainless steel have extremely low nickel release rates, making them safe for sensitive skin. Unlike lower-grade stainless steels or plated jewelry, our pieces won't cause irritation or allergic reactions.
2. Long-Lasting Beauty
These grades maintain their luster and don't degrade over time. Your ATLASECA jewelry will look as beautiful years from now as it does today.
3. Everyday Wearability
You can shower, swim, exercise, and sleep in your ATLASECA jewelry. These grades are built to withstand your active lifestyle.
4. Ethical and Sustainable
Stainless steel is 100% recyclable and doesn't require mining precious metals. It's a responsible choice for conscious consumers.
The PVD Coating Advantage
While 316L and 304 stainless steel are already incredibly resistant to tarnishing, we take it one step further with PVD (Physical Vapor Deposition) coating on select pieces.
What is PVD Coating?
PVD is an advanced vacuum coating process that bonds a thin layer of material (like titanium or zirconium) to the surface of the stainless steel at a molecular level. Unlike traditional plating methods, PVD creates an incredibly durable, permanent finish.
Benefits of PVD Coating on Stainless Steel
Prevents Tarnishing
The PVD coating creates an impermeable barrier that protects the stainless steel from oxidation, moisture, and environmental factors that can cause discoloration.
Enhanced Durability
PVD coatings are harder than the base metal, making your jewelry even more scratch-resistant and long-lasting.
Maintains Hypoallergenic Properties
The coating is biocompatible and doesn't compromise the skin-safe qualities of the stainless steel underneath.
Beautiful, Lasting Color
Whether it's gold, rose gold, or black, PVD-coated jewelry maintains its color without fading, peeling, or wearing off like traditional plating.
Eco-Friendly Process
PVD coating is a clean, environmentally responsible process that doesn't use harmful chemicals or produce toxic waste.
How to Care for Your ATLASECA Stainless Steel Jewelry
One of the best things about 316L and 304 stainless steel with PVD coating? It requires minimal maintenance:
- Daily wear: Safe to wear 24/7, including in water
- Cleaning: Simply wipe with a soft cloth or wash with mild soap and water
- Storage: Store in a dry place; no special anti-tarnish bags needed
- Avoid: Harsh chemicals like bleach (though occasional exposure won't damage it)
