Stainless Steel
Once acquired from Rolex’s steel suppliers, Rolex casts and scans it utilizing an electron microscope that is able to detecting the slightest structural or floor defect. Rolex has been identified to ship metal again when it doesn’t meet their exacting specifications. After casting and inspection, the metal is then re-melted in a vacuum to purify it and remove any inclusions that would diminish its corrosion resistance and lead to issues in sprucing. Noble steel wristwatches such as gold or platinum watches don’t have corrosion points, however base metal does. Until the widespread use of stainless-steel, older watches utilized primitive stainless casebacks and a few kind of base-steel case.
Steel Vs. 316l In Watchmaking Industry
904L chrome steel doesn’t machine properly which makes it costlier to producer and fabricate into a wrist watch. Subsequently, Rolex designs its own instruments to manufacture 904L watch circumstances SA240 316 Stainless steel plate, casebacks, and bracelets including a 250 ton press to stamp the initial cases. 361L metal is the trade normal steel for wristwatches.
Only a small number of manufacturers use 904L stainless steel quite than 316L, but Rolex is the model that screams the very best about it. In 2003 Rolex’s whole manufacturing line modified to 904L steel. Two-tone Rolex watches have their bezels, winding crowns, and heart bracelet links craft from 18-karat gold, while the center case and outer hyperlinks of the bracelet are made from 904L stainless steel.

- Rolex aficionados have commented that some people sweat extra acidic than others as demonstrated by discovering pits in 316L wrist watches making 904L stainless extra fascinating.
- Harder and extra rust and corrosion-resistant than different steels, this 904L steel can take and maintain a polish extremely properly.
- Rolex calls 904L chrome steel a “corrosion-resistant superalloy.” 904L differs from 316L because of extra Chromium, Molybdenum, Nickel, and Copper that offers it improved resistance to acids.
- 316L is taken into account a more durable, more durable, “marine grade” steel, however it doesn’t have luster and acid resistance of Rolex’s 904L stainless steel.

Rolex aficionados have commented that some people sweat more acidic than others as demonstrated by discovering pits in 316L wrist watches making 904L stainless extra desirable. Harder and extra rust and corrosion-resistant than different steels, this 904L steel can take and maintain a polish incredibly nicely. This is why metal Rolex watches look different than different metal watches. Rolex calls 904L chrome steel a “corrosion-resistant superalloy.” 904L differs from 316L due to further Chromium, Molybdenum, Nickel, and Copper which gives it improved resistance to acids. 316L is taken into account a more durable, harder, “marine grade” steel, however it does not have luster and acid resistance of 904L.
Is 904l better than 316l?
The 316L Stainless steel is far less scratch resistant than the 904L because it has a much higher Rockwell hardness. The main advantage of 904L over 316L is its resistance to acids: “The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid.”
Unlike the remainder of the business, Rolex makes use of 904L chrome steel for qualities that Rolex believes surpasses the trade commonplace. Nowadays, most stainless-steel wristwatches are made from 316L stainless steel, and for a time, so was Rolex. Even though 316L metal was created in order to forestall rust and pits from salt water and sweat, Rolex was discovering excess wear in the case back threads and watch case. Salt and different minerals are the catalysts needed for corrosion and deterioration of the threads holding the case back. They may clearly see that gold and platinum watches didn’t have this corrosion issue, so it needed fixing.
In 2003 their entire production line modified to 904L, although it was as early as 1988 that they released their first 904L metal watch with a number of versions of the Sea-Dweller. Once received from Rolex steel suppliers, Rolex casts and scans it using an electron microscope that’s capable of detecting the slightest structural or floor defect. Rolex has been recognized to ship steel again when it does not meet its exacting specs or when impurities are discovered.
What watches use 904l steel?
1. Rolex. One of the metals developed by Rolex is a material known as Rolesium, a combination of 904L stainless steel superalloy and 950 platinum. Rolesium was used in the 40-mm diameter Oyster case of the Rolex Yacht-Master seen here.
