Title: Stainless Steel
Post by: Watchnewby on August 05, 2011, 02:18:22 PM

To my understanding, stainless steel (ss), which is used mainly in watches, is a kind of alloy made up from a couple of elements like iron, nickel, chromium, manganese etc.

I read somewhere that mentioned tegimented steel. Is this a kind of ss?
Is it similiar or different to the process of ice hardening steel?

Currently, I read that ceramics are getting more popular in watch making as it is one of the hardest material in the world. Do you think that the watch making industry will be moving from ss to ceramic in the future?

Those mentioned are only 3 out of tens of grades used in the industry. Those listed are commonly used in watches. I wonder if the watch makers forge the SS themselves or contract to the foundries.

Check out this youtube on Rolex's inhouse use of 904L. http://www.youtube.com/watch?v=9UuDJl93Z1g

Lowlex has also been alloying their own gold in-house as well for QC. And I must say, the new solid bracelet links (rather than hollow) are not flimsy at all :thumbsup:
