Steel cannot rust nearly that fast, you'd need at least 4 days before signs were apparent. Thermal shock (rapid heating and cooling) would be far more feasible in such a short space of time.

Grade 100 9/32 chain (some of the smallest industrial chain available) can roughly withstand 12 kilonewtons of force, which is comparable to:
 * ~ average force acting on a baseball being hit by a bat ( 18000 N )
 * ~ 1.1 × estimated force of a bite from a great white shark (Carcharodon carcharias) ( 18 kN )

4 kN is already enough force to break bone, so it's not going to break with brute force. Also because it's a chain, targeting specific sections is a pain in the ass because the whole thing will bend backwards on impact, making it tricky to hit and break without pinning it down first.
