The choice of materials is a fundamental element in the design of a watch. It influences its durability, comfort and aesthetics. Among the most popular alloys in watchmaking, 316L stainless steel stands out as an essential reference.
Why is it used so much by watch brands? What are its properties that make it a superior material to other types of steel? This article reveals everything you need to know about 316L stainless steel and its essential role in the manufacture of high-end watches.
What is 316L Stainless Steel?
316L stainless steel is an alloy of iron, chromium, nickel and molybdenum, designed to resist corrosion and provide optimum strength.
Composition of 316L steel:
- Iron (Fe) : Main element, guaranteeing the metallic structure.
- Chromium (Cr) - 16 to 18% : Provides resistance to oxidation and rust.
- Nickel (Ni) - 10 to 14% : Improves malleability and corrosion resistance.
- Molybdenum (Mo) - 2 to 3% : Increases resistance to aggressive environments (humidity, salt water, sweat).
Difference with other stainless steels
Stainless steel comes in several varieties, but not all have the same properties.
- 304 steel : Less resistant to corrosion than 316L, it is often used in everyday objects but less suitable for high-end watches.
- 904L steel : Even more resistant to corrosion than 316L, it is used by certain luxury brands such as Rolex, but its cost is significantly higher and its machining more complex.
316L steel therefore stands out for its excellent balance between strength, durability and controlled cost , which makes it a preferred choice in watchmaking.
The Advantages of 316L Steel in Watchmaking
Exceptional Resistance to Corrosion
One of the main advantages of 316L stainless steel is its ability to resist corrosion, even in the most aggressive environments.
- It does not rust, even in prolonged contact with water, humidity or sweat.
- It is ideal for watches worn outdoors, especially diving or sports models.
- Its molybdenum content allows it to better resist saline environments, thus avoiding premature oxidation.
Robustness to All Tests
316L steel is a material known for its strength. It can withstand everyday impacts and scratches perfectly, while retaining its original appearance.
- It is more impact resistant than softer alloys such as aluminum or some precious metals.
- Its hardness allows watches to retain their shine and structure for years.
- It does not deform easily, ensuring excellent support for the case and bracelet.
A Hypoallergenic Alloy
Prolonged contact with certain metals can cause irritation or allergic reactions. 316L stainless steel is designed to limit these inconveniences.
- It contains a low proportion of nickel, considerably reducing the risk of allergies.
- It is widely used in jewelry and medicine for its biocompatibility.
- It is perfectly suitable for people with sensitive skin.
A Premium Aesthetic Rendering
316L stainless steel provides a premium finish whether polished or brushed.
- Its natural shine brings a touch of timeless elegance.
- It can be worked in different ways to obtain a shiny, matte or satin effect.
- It matches different types of dials and bracelets for a refined look.
316L Steel vs Other Types of Steel: Comparison
| Steel type | Corrosion resistance | Hardness | Aesthetic | Cost |
|---|---|---|---|---|
| 304 steel | Average | Good | Standard | Weak |
| 316L steel | Excellent | Very good | Premium | AVERAGE |
| 904L steel | Superior | Excellent | Very premium | Pupil |
316L steel therefore represents the best compromise between quality, resistance and accessibility , which explains its adoption by many watch brands.
