Your right about the wire being rated for ambient temperature, but at around 400 degrees, the multiplier is .82, or still around 45 amps for 14 ga. Placed into conduit would further reduce the rating, but I don't have those numbers handy.
I think one reason the hi temp wire is rated for higher amps is that it is a
"stranded nickel-plated annealed copper conductor with an
insulation of glass-reinforced mica tape covered with a braided fiberglass
jacket". This quote from the McMaster web site.
