The iron pillar of Delhi is a metal structure 7.21 metres (23 feet 8 inches) high with a 41-centimetre (16 in) diameter that was constructed by Chandragupta II (reigned c. 375–415 CE), and now stands in the Qutb complex at Mehrauli in Delhi, India.

It is said that he brought it here to adorn his capital city at Lal Kot, the ruins of which are visible in the vicinity, and the great Vishnu Temple that he built here.
Initially, the corrosion rate of iron is high due to the presence of slag particles. This results in enhancement of surface P content. In the presence of P, the formation of a protective amorphous compact layer of δ-FeOOH, next to the metal surface, is catalyzed and this confers the initial corrosion resistance.
The Iron Pillar of Delhi: A Testament to Ancient Indian Metallurgy Standing tall amidst the Qutub Minar complex in Mehrauli, Delhi, the Iron Pillar of Delhi is a remarkable marvel of ancient Indian metallurgy.

The IRON Pillar located inside the Qutab Minar Complex is a protected monument and one cannot touch the Iron Pillar . There is a ticket requirement for entering the Quatb Minar Complex .
To prevent oxidation and breakdown of metal products, such as handrails, tanks, appliances, roofing, or siding, you can choose metals that are “rust-proof” or, more accurately, “corrosion-proof.” Four basic types of metals fall into this category: Stainless steel. Aluminum metal. Copper, bronze, or brass.
Iron rusts while gold does not because, .... Iron is more chemically reactive and reacts with oxygen and moisture in the air to form rust, whereas gold is a noble metal, chemically inert, and resistant to oxidation. Gold forms a stable oxide layer that is unaffected by weathering.
An iron pillar placed in the UNESCO-listed Qutub Minar complex in New Delhi has long fascinated scientists for surviving over 1,600 years without rust. Standing tall at 7.2 metres and weighing six tonnes, the iron pillar predates the complex it resides.
The Mehrauli Archaeological Park is an archaeological area spread over 81 hectares (200 acres) in the Mehrauli neighbourhood of the South Delhi district of Delhi, India.

They found that the pillar, primarily made of wrought iron, has a high phosphorus content (about 1%), and lacks sulfur and magnesium, unlike modern iron. Additionally, ancient craftsmen used a technique called “forge-welding.”
The oldest inscription on The Iron Pillar is in Sanskrit, written in Gupta-period Brahmi script. " The inscription describes the king as a devotee of the god Vishnu, and records the erection of a dhvaja ("standard", or pillar) of Vishnu, on a hill called Vishnupada ("hill of the footprint of Vishnu").
In most environments, stainless steel retains its strength and appearance for over 50 years. It can take up to 1,000 years to naturally break down in the right conditions. That's why you'll see it used everywhere, from kitchens and workshops to commercial cladding and marine engineering.
100% pure gold (24 karat) is a distinct, rich, deep, metallic yellow color, often described as butter-yellow or yellow-orange, that is shiny and pure, but too soft for most jewelry, so other metals are added to create the softer yellow, white, or rose gold colors seen in jewelry.
Patination composition varies with the reacted elements and these will determine the color of the patina. For copper alloys, such as bronze, exposure to chlorides leads to green, while sulfur compounds (such as "liver of sulfur") tend to brown.
Although it may be rare, we have a few people who are allergic to zinc metal. In such cases, therefore, it's unsafe. Nonetheless, if you don't have a metal allergy, then the zinc alloy should be safe. Generally, the zinc metal will contain lead, nickel, copper.
How do we come to know that the iron pillar at Mehrauli was made about 1500 years ago?
This pillar was made nearly 1500 years ago. The date is known because there is an inscription on the pillar mentioning a ruler named Chandra, who probably belonged to the Gupta dynasty.
