What is the different between 904L steel used by Rolex and 316L used by many other manufac
An answer frm the ROLEX FAQ frm other forum ...........................
What type of Stainless Steel does Rolex use?
Most watch manufacturers use stainless steel 1.4435 or 316L. Rolex uses stainless steel 1.4439 or 904L which is slightly different from 1.4435. Steel 904L and 316L have the same grade of hardness. The level of nickel discharge with 904L is slightly higher, causing an increased chance of allergic reaction when worn by people sensitive to nickel. While technically 904L is more corrosion resistant, this is typically a concern is in industrial applications using steel in equipment for handling chlorides, sulfur dioxide gas or other toxic materials. Almost no watch manufacturers except Rolex consider it worth using the 904L steel, especially given that the price for 904L is approximately three times that of 316L.
It still does not answer my question...............
Is 904L steel better than 316L ? What are their advantages? Why Rolex uses 904L grade steel? Yes the above answers my question but I too always wander what type of grade steel AP & other manufacturer uses since we are paying a lot for our beloved watch.
As u all know I purchase a Rolex GMT Master ll-C and I also have other watches such as AP, GP, JLC & Panerai.

Here's what I understand...
The 316L Stainless steel is far less scratch resistant than the 904L because it has a much higher Rockwell hardness. The 316L has less nickel in it and is far brighter in appearance and tends to stay that way. Nickel can be an irratant to some. The 904L i...
i have heard from a jeweler
that has been doing watches for over half a century that the old steel pitted with age and the new has resistance against pitting.. or so he thinks as he has yet to see a piece with the 904L with pitting.. it was a brief conversation we had so i hope im r...
