No it is not. "solder melts above 327C/621F" is just wrong, even for
leadfree solder.
It may be the temperature you set on your soldering iron, but the
melting temperature is much lower:
<http://en.wikipedia.org/wiki/Solder>

Typically you'd have a melting temperature of 220°C or below and a
reflow temperature of maybe 250°C for leadfdree, a little less for
leaded solder. If you make the hotplate much hotter you'll only toast
your boards a nice brown.

I would also prefer to avoid non-stick coating for a hotplate just to
get a bigger safety margin, a bare aluminium plate works well because
solder will not stick to it. You can put it on a cheap electric
cooking plate or even an old upside-down clothes iron.
