Why doesn't stainless steel jewelry rust?
Stainless steel has become an essential material in modern jewelry. Robust, elegant and affordable, it appeals to more and more people. But one question often comes up: why doesn't stainless steel jewelry rust? In this article, we will explore the properties of this metal and understand why it resists corrosion so well.
Stainless steel: an alloy with unique properties
Stainless steel is a metal alloy composed mainly of iron, carbon and chromium . It is this last element that makes all the difference! As soon as a stainless steel jewel is exposed to air, a protective layer of chromium oxide instantly forms on its surface, preventing oxidation and rust.
An alloy containing chromium: the key to resistance
Unlike other types of steel, stainless steel contains at least 10.5% chromium . This component creates an invisible, self-healing barrier that protects the metal from external aggressions such as water, humidity and sweat . Result: the jewelry retains its shine without rusting!
Why doesn't stainless steel rust when exposed to water?
It's a common misconception that any metal exposed to water will eventually rust. However, stainless steel is designed to resist moisture thanks to its protective film.
- A layer of chromium oxide that regenerates : if the jewel is scratched or slightly damaged, this barrier reforms by itself upon contact with oxygen.
- Low free iron content : Unlike conventional metals, stainless steel does not contain pure iron that can oxidize quickly.
This means you can wear your jewelry in the rain, in the pool or even in the shower without worrying about it turning black or rusting.
Stainless Steel Against Sweat and Chemicals
When you wear jewelry every day, it is exposed to several elements that could alter it:
- Perspiration and skin pH : Some acidic skins accelerate the oxidation of metals, but stainless steel remains insensitive to these variations.
- Cosmetics and chemicals : perfumes, creams and hydroalcoholic gels can tarnish some jewelry. With stainless steel, this risk is considerably reduced.
👉 Tip : Although very resistant, it is always recommended to wipe your jewelry after prolonged contact with chemical substances to preserve its shine.
Comparison with other materials: gold, silver and classic steel
Here is a comparison chart between stainless steel and other metals commonly used in jewelry:
| Metal | Rust resistance | Sensitivity to scratches | Price |
|---|---|---|---|
| Stainless steel | Very resistant | Average | Affordable |
| Gold | Does not rust | Weak | Pupil |
| Money | Sensitive to oxidation | Average | Pupil |
| Classic steel | Rusts easily | Average | Affordable |
We note that stainless steel is an excellent compromise between durability, aesthetics and price!
How to maintain your stainless steel jewelry to keep it shiny?
Although stainless steel does not rust, it can become slightly dirty or tarnished over time. Here are some tips for maintaining it:
- Regular cleaning : a soft cloth soaked in soapy water is enough to remove impurities.
- Dry thoroughly after each wash or contact with water to avoid streaks.
- Avoid abrasive products : use a microfibre cloth rather than a rough sponge.
