What is 904L material?
Alloy 904L (UNS N08904) is a superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance.
Is 904L steel magnetic?
Alloy 904L performs better than other austenitic stainless steels due to the higher alloying of nickel and molybdenum. The grade is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.
How hard is 904L steel?
Its popularity in these areas comes from the properties which make it resistant to rust and corrosion. 904L steel takes the resistance to corrosion up a notch….316L VS 904L Steel Composition:
| 316L Steel | 904L Steel | |
|---|---|---|
| Hardness (Rockwell) | 95 | 70-90 |
| Hardness (Brinell) | 217 | 150 |
What is AL6XN material?
AL6XN is a superaustenitic stainless steel with outstanding resistance to chloride pitting, crevice corrosion and stress corrosion cracking. AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.
Can a Rolex get scratched?
they’re like any other steel watch. they scratch just as easily. some of them have ceramic bezels, and that portion of the watch is highly scratch resistant, but that’s it. the cases of rolex are like any other steel watch.
When did Rolex start using 904L?

904L STEEL In 1985, Rolex became the first watchmaking brand to use this steel from the 904L family for its cases.
Can Rolex go in saltwater?
Water is the natural element for a Rolex with a metal bracelet, including the salt-water of the sea and ocean. All Rolex wristwatches are waterproof to depths of at least 100 metres for Oyster Perpetual models, and 50 metres for Cellini models.
What is SMO material?
Sandvik 254 SMO is a high-alloy austenitic stainless steel developed for use in seawater and other aggressive chloride-bearing media. The steel is characterized by the following properties: Excellent resistance to pitting and crevice corrosion, PRE = ≥42.5* High resistance to general corrosion.
