This is not pure iron but a special steel.
The Iron Pillar in Delhi, India is not significantly rusted due to a protective layer of passive iron oxide formed by a high phosphorus content in the iron. This layer acts as a barrier against further corrosion. Additionally, the climate conditions in the area have also played a role in preserving the pillar.
corrosion resistance by hydrogen phosphate forming on the high phosphorus content iron
highly purified iron 99.09 percent pure, that hasn't rusted in thousands of years.
because the iron pillar did not get rusted after so many years. it is corrosive resistant due to its high phosphorous content
Rusted cast iron.
Rusted iron is generally weaker than non-rusted iron, as the rust (iron oxide) can create a brittle layer that compromises its structural integrity. This degradation makes rusted iron more susceptible to breaking or crumbling under stress. While some areas may still retain strength, overall, rusted iron is considered less durable and more easily broken compared to its non-rusted counterpart.
Rust on iron is a hydrated iron oxide.

Rusted iron, or iron oxide, does not contain the same magnetic properties as pure iron. The presence of rust creates a barrier between the iron atoms and the magnetic field, reducing the overall magnetism. Additionally, the rust itself is not magnetic, further decreasing the attraction to a magnet.
Rusted Iron that rusted over thousands of millions of years!
it will be rusted because of the H2O and oxgen
