I'm looking at my Small Parts catalog section on metals and it looks like 
"it depends"  They all contain chromium (12% minimum)  sometimes sulphur, 
Molybdenum, nickel.  There's a high carbon chromium steel that can be 
highly heat treated to a high hardness (tooling, cutlery, etc)  That 
sounds possibly brittle, but I doubt they would make fasteners out of 
that.  Here's the first bit of the intro, I think you'll find it 
reassuring:

Maybe not for flywheel bolts but for the fan, why not?
