Your average single based IMR propellant has an adiabatic isochoric flame temperature of around 4700°F, even double based small arms propellant rarely gets over 5000°F.
M8 tank gun propellant has a flame temperature of around 6000°F, but the stuff is 43% nitroglycerine. (Double-based WC846 Ball propellant is only 10% nitroglycerine, and heavily deterred, yielding a much lower flame temperature.)
But, you are on the right track - The melting point of steel is around 2500°F.
