I am currently writing a manuscript, and would like to know whether guns made out of steel, burn or melt when exposed to flames. Thanks.
Any steel will burn in the Presence of pure oxygen and high heat, that's how a cutting torch works.
Yes they melt and rather easily. Guns are made by melting steel and many police departments destroy confiscated guns by melting them.
Steel guns would be very hard to melt, and impossible to burn, in any circumstances you could reasonably expect them to encounter at least. If you expose them to a flame they'll just get carbon on them from the flame, turning them black...
Steel melts around 2500°F (1370°C). That's hotter than most normal fires (obviously, your steel pots don't melt on the stove, do they?) but a blowtorch or something like that could do it.
