The iron pillar in Delhi is not rusting due to the presence of a protective layer of passive iron oxide that forms on its surface, acting as a barrier against corrosion. This layer is believed to have formed due to the unique composition of the iron used in its construction, as well as environmental factors.

The pillar in Delhi, known as the Iron Pillar of Qutub Minar, is made of wrought iron and is a testament to the advanced metallurgical skills of the Gupta period. The pillar's resistance to corrosion is due to the high phosphorus content in the iron and the presence of a protective passive layer. This indicates that the Guptas had a sophisticated understanding of metallurgy and metalworking techniques.
The base of the pillar is tied to its foundations by small pieces of iron. It rises to a height of 7.20 m, with 93 cm buried below the present floor level

Imperial Gupta Dynasty......in 4th century.......
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.

The iron pillar of Delhi dates to 912 BC. The medieval period of European History dates to 476 to 1453 AD. There are periods of other places referred to as medieval because of some analogy to the European Middle Ages, but I do not know the dates for one in India. There is a link below.
