[TheForge] Brushed finish

Thu Feb 13 14:21:00 2003

Because SS is not a uniform material.  All SS that doesn't rust is =
passivated.  Literally, the iron is etched out of the surface, leaving =
behind chromium and nickel.  These form clear oxides - no rust.  Cut =
through this outer layer and expose the iron and bingo, rust.

Now wheter wire brushing WILL cut through this outer layer, I don't know.  =
(A mild steel wire brush deposits mild steel on SS, so that's a different =
thing.)  However, an abrasive pad certainly will cut through the outer =
layer, because the abrasives they put on those things are much harder than =
SS.

How does a rough finish change the inherent property of SS? I know that
if you use a plain steel wire brush etc for the brushed look you can get
some particles of steel in the SS that will rust,, but if you use a SS
wire wheel you should not have this issue.
