If you mean in solid ice, then there are three reasons.
First ice is cold, so chemical reactions are slowed down a lot.
Secondly ice is an electrical insulator. Rust depends on a electrolytic process where water supplies a charge to the rust site.
And thirdly, ice is solid and impermeable to oxygen, so oxygen, which is needed for rusting, cannot get to the iron.
Iron in a water and ice mixture will rust, though slowly, as the electrolytic process and the oxygen will both be present.
Steel will corrode as the iron in it is more reactive than copper.
damp
steel
Steel is lighter, less brittle, doesn't corrode (rust) as quickly and is easier to shape and form.
Steel wool corrodes from water because the water has oxygen. If the steel wool is in contact with both the water and oxygen it will begin to rust rapidly. The rusting will take a while. It will take between 5-7 days.
No, gypsum does not corrode stainless steel.
Steel will corrode as the iron in it is more reactive than copper.
damp
u.s.
No
Practically impossible
Moisture and oxygen.
yes
Zinc.
Rust, which is ferric oxide.
No, because they are plated.
there is more oxygen in water
