Inconel (generic term for a rather large series) is a nickel based
superalloy - it has very good high temp properties(>1200F) when compared
to stainless steel - the largest market for most of the alloys is in 
aircraft turbine engines - very good resistance to oxidation to ~2000F

Not a cheap material - you wouldn't want to make too many mistakes
in fabricating.
