How does the metal of a baking sheet get burned?
My kid wanted to boil a kettle of water on the back burner. An empty baking sheet was sitting on the front (we had baked some cookies earlier). They accidentally turned on the front burner instead of the back, and walked away for a minute.
How does a baking sheet itself get burnt? Are stove tops a lot hotter than 500 degrees?
Best Answer
A natural gas flame is about 1950 C or 3540 F, so yes, a lot hotter than 500 degrees. (source)
Electric stoves will get red hot, indicating a temperature in the range of about 500-900 C or 770-1220 F. (source)

Why is my baking sheet burning?
In short, your cookies may have burned on the bottom because your oven temperature readings are off, your cookie sheet is too dark, your cookies were baked on a lower rack, the heat was too high, or you baked the cookies right on the sheet without any parchment paper.Do cookie sheets burn oven?
The cookie sheet may be too large for the oven and not allowing sufficient heat circulation. The heat is trapped under the pan and the cookies will burn on the bottom before the tops are brown. We recommend at least 1 to 1 1/2 inches around the cookie sheet.How do you clean a burnt baking sheet?

Make sure your stovetop is clean.Residue from spilled sauces, sugary syrups, and other food will burn if exposed directly to the heat of the stovetop burner. This will be a hassle to clean off your stovetop, but more to the point, it could also end up burning to the bottom of your pots and pans.How To Clean Sheet Pans

Answer 2
I take it this is an Induction cooktop/electric glass cooktop.
"Induction cooking is performed using direct induction heating of cooking vessels, rather than relying on indirect radiation, convection, or thermal conduction. Induction cooking allows high power and very rapid increases in temperature to be achieved, and changes in heat settings are instantaneous" - Wikipedia, Link
An electric glass cooktop uses electricity to first heat a burner. The heated burner then heats the cookware in contact with it - baconappliance.com, LINK
Because it is directly heating the cooking vessel, this induction stove will "cook" your metal directly, not boiling what is inside of it. It's the same principle as all kinds of stoves basically, it cooks your pot.
So, without anything inside of it the heat will be rise quickly (and because it's thin nothing like a pot), it could reach up to 260C (500F)Link. But this is depending on your stove because some stove doesn't have thermocouple to check the temperature it only adjusting the power of your induction, and it will rise quickly to 300C or who knows in max setting on the knob..
The black burns will show up because it reaches the temperature to burn the outer layer of steel because lacks cooling/food inside to cook it.
Edit:
"How hot does a stovetop get on high? I have found that using an IR thermometer to read pan bottom temperature after 5 minutes of heating (the temperature is no longer rising), that high corresponds to 375 degrees F, medium-high to 330 degrees, medium to 300 degrees, and low to about 275 degrees." - expandusceramics.com
so either you have the induction cooker that has more capability to reaching more temp, or you have an electric stovetop that has a broken thermocouple or it sets to max temp.
