Sae 904l Stainless Steel
Rolex was not the first watch brand to use 904L chrome steel. That honour, as so many who Rolex claims for itself, goes to Omega. The original Omega Seamaster PloProf 600M was created from a single block of 904L stainless-steel.
For out of doors furnishings like rails and bollards, chrome steel is an ideal corrosion-resistant material, but it will only withstand long-term exposure if the grade is suitable for its environment. 304 is a cheap and sensible choice for most environments, but it doesn’t have the chloride resistance of 316. The barely higher value level of 316 is properly worth it in areas with high chloride exposure, especially near the ocean or by heavily salted roadways. Each software for stainless steel has unique calls for and wishes a stainless-steel that’s up to the duty. In the tip, it stays a little bit of a mystery why certain Rolex watches aren’t obtainable.
Prices went by way of the roof for this watch, but at present it is a watch you possibly can easily find. With ups and downs, the Rolex Submariner and GMT-Master fashions have been obtainable as well in chrome steel. Full gold or bi-shade watches have not likely been an issue. When I bought a new Rolex GMT-Master II in 2006, they had been simply in the home windows in all places for instance.
- This steel grade needs to be solution treated following cold working, to achieve most stress corrosion cracking resistance beneath critical environments.
- The corrosion resistance of grade 904L is intermediate between super austenitic grades, with 6% molybdenum content, and standard 316L austenitic grades.
- These grades can be readily bent to a small radius beneath chilly circumstances.
- Grade 904L is less proof against nitric acid than grades 304L and 310L, which are free of molybdenum.
- Although subsequent annealing isn’t required generally, it should be carried out when the fabrication is performed under severe stress corrosion cracking circumstances.
What type of stainless steel is 316l?
While Rolex is the most well known watch brand in the world, Patek Philippe is at a whole different level of sophistication and class. Rolex is great because it makes everything in its watches in-house and at the highest level of quality. They achieved remarkable quality levels even though they mass produce watches.
After all, they’re an organization that produces so many watches per yr in-house. Could Rolex maybe, with all the bi-colour models in inventory, restrict production for these and enhance production for all stainless-steel? Also licensed sellers (we requested a couple of) maintain coming again with the identical reply, that the demand is just too excessive for these watches. We just hope that Rolex can remedy this problem and begin the supply of their stainless steel sports activities watches. We’d love to see it for the new fashions, just like the GMT-Master II with Pepsi bezel, but also for longstanding models like the GMT-Master II, the blue & black version of that watch, the Submariners, etc.

Nobody exterior Rolex (or Wilsdorf foundation) is aware of the precise number, however our estimate is between 800.000 and 950.000 watches a 12 months. We also think that this quantity is ‘dynamic’, which means they’ll go up and down depending on the economic local weather. We’ve seen some years that weren’t simple, probably additionally not for Rolex. With all due respect, it’s a matter of planning capability and maybe scaling up the production for these models.
Does Tudor use 904l steel?
Alloy 316/316L (UNS S31600/ S31603) is a chromium-nickel- molybdenum austenitic stainless steel developed to provide improved corrosion resistance to Alloy 304/304L in moderately corrosive environments. It is often utilized in process streams containing chlorides or halides.
Lange & Söhne (or fill in an haute horlogerie brand) watche, that need plenty of handbook interference and finishing. When we asked Rolex about this during our assembly with them in Baselworld, they simply acknowledged these watches are in excessive demand and that they have been conscious of the supply downside. When the Yachtmaster in steel and platinum came out in 1999, it was just not there for a long time. Sometimes, it is only a short interval that there isn’t a availability, like the Rolex Milgauss that was re-introduced in 2008.
