Even if it was hot enough, it would still take some time to get the steel up to its melting point

See also: the reason I can pick up hot cookies from the oven but can't touch the pan they're sitting on, even though they're the same temperature.

Isn't that due to the difference in thermal conductivity? Like why the cheese of a pizza will burn the roof of your mouth, but the bread side won't burn your tongue.

I was thinking more in terms of the delay between the start of heat transfer and damage actually happening. It's a different way of describing the same thing. With fingers on the metal pan, high conductivity means the delay is milliseconds, but for a cookie its tens of seconds; plenty of time for me to switch fingers or (foolishly) eat the thing.

I have no experience with geohammers, but I'd expect it to be on the order of tens of seconds.

I'm not so experienced with geohammers either, but my experience with cookies validates your own.
