Is it true you can use liquid nitrogen to break a steel like chain?

I saw it in movies where they use liquid nitrogen to froze chains then they used hammer to break the chain. Is that true?

yes, liquid oxygen works too, the metal gets so cold that it will shatter with even a slight touch.

we used to play with liquid oxygen a lot at work. we froze clothes and leaves and flowers and all sorts of other things and shattered them.

Liquid Nitrogen is <very cold> (under -321°F)
