ARF and 904L

[P4GTR]

It's not true that 904L less scratch! It's also not harder than 316L.
There are also variants on 904 Steel.
But in fact u are right about everything else.

Another hobby of mine is knives. I know with the steels used, there is a direct trade off between edge retention, durability/hardness, and the steels ability to withstand the elements and not tarnish. Harder steels in the knife world tend to have higher carbon content. High carbon tool steel used for tools, ball bearings and such while harder, are more prone to corrosion. So a corrosion resistant formulated steel such as 904L should perhaps be softer and scratch even easier than 316. My 904L sea dweller has accumulated just as many desk dives as any other Rolex bracelet I've worn. I do appreciate knowing it's likely to hold up well if worn in the ocean.

In a few years Rolex will start using a new stainless steel and claim it is better than 904L Stainless Steel and charge more for it.
