If so there are many sites to look at. Use Google.

What it looks like is rusty steel. The catch is, it won't keep rusting until it's gone like a normal steel would. I recall seeing a big arch bridge in Austin made of the stuff.
Advantages: You don't have to paint it.
Disadvantages: You're stuck with the color that it is. It will put rust stains on anything below it also. Raw material cost is higher than regular steels.
Applications: Bridges, buildings, etc.
Did you have some specific application in mind?

Definitely not good when exposed to salt or frequent wetting; you wouldn't want it on a low bridge over a stream.
I've heard that local air quality plays a large part in what color it'll turn--chocolate brown, purplish, orangish. Make sure you blast all the mill scale off visible surfaces or it will look like crap for decades.
There's a slight cost premium on weathering steel plate, but it's generally considered to be made up for in painting costs, especially when you take in lifetime costs--a painted bridge will need repainting every 10-20 years.
