Stalin Rolex
Comrades,
Hi, what do we know about the steel our watches are made from? I seem to remember it being refered to as 'surgical stainless steel'. What's the latest spec'? How has it developed from the early Oysters? Are the bodies and bracelets carved from the same stuff? Is it the Chromium that gives that shine? (plus some elbow grease!) There must be a 'man of steel' that can enlighten us. Regards, FB. |

I think they use 316L Grade Steel (Low Carbon).
This is generally 18% Chromium, 2% Molybdenum, 14% Nickel (though the specification allows for a couple of % variation and smaller amounts of Manganse, Silicon, Phosphorus, Chromium and Nitrogen) I am sure that Rolex have an exact specification for the 'mix' and manufacture of their particular 316L Grade.

Maybe I am misinterpreting this question, but my understanding is that Rolex uses 904L grade steel, while everyone else uses 316L. There has been debate about this point because Rolex has claimed that it uses this steel for a reason, that it's functionally better/tougher, etc., but all other manufacturers seem to disagree on this point. Please excuse my disagreement as being in the spirit of wanting to impart accurate information rather than trying to be argumentative. If I have missed a point, I beg your indulgence. However, I think you'll find Rolex uses 904L.

I beleive that 904 is used,and in steel circles it has a better ability to withstand chemicals and corrosion etc.
The polished effect is just stainless steel polished to get the high lustre. In regards to the chemical breakdown of the steel used I have no idea,and to be quite honest would mean nothing to me. Aaron Last edited by AJC; 21 September 2006 at 10:42 PM.. |

Well yes there is quite a debate about the different steels in watches.And yes Rolex does use 904L steel but only certain parts.Myself worked in the specials steels industry for almost 30 years and below is part of the quote.
Quote from Rolex employee in 2002. At the moment, we have several companies all over the world, serving our needs for stainless steel. The watch case back and bracelets are all made of X2CrNiMo17-12-2 which is the best compromise between the attributes of the variant materials. As usual, the steel is melted under vacuum, so we get an very pure base, which is easy to handle and allows an perfect polishing. And the same procedure as in every good (expensive <gold>) company X2CrNiMo17-12-2 Is the technical specification for 316L S.S One of those providers is http://www.boehler-thyssen.ch/

It therefore appears that Rolex favour a 17% Chromium, 12% Nickel, 2% Molybdenum mix, within the specification for 316L Stainless Steel.

Great info, pal. Do you have the composition details on the 904L grade?
Thanks - JJ

Technical formula for 904L X1NiCrMoCuN25-20-5. Fe,Iron <0.02% C,Carbon 19-23% Chrome, 23-28% Nickel, 4-5% Mo,Molybdenum <2.0% Mn,Manganese. <1.0% Si,Silicon. <0.045% P,Phosphorus <0.035% S,sulphur 1.0-2.0% Cu,Copper 904L is a non-stabilised low carbon high alloy austenitic stainless steel. The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid. It is also highly resistant to chloride attack - both pitting / crevice corrosion and stress corrosion cracking. This type of steel is used mainly in these industries. Processing plant for sulphuric, phosphoric and acetic acids. Pulp and paper processing. Components in gas scrubbing plants. Seawater cooling equipment. Oil refinery components. Wires in electrostatic precipitaters.

OK, but he sure did hassle them a lot... "Where's your list???" "Did you send in that list, Tosser?" "I have to put up with people who can't even send in a list!"... And this was all within a 15-minute period!!!
