Also...do you know about the idol in the somnath templet(Gujarat,India) which hanged in mid-air with no support???

SOMNAT. A celebrated city of India, situated on the shore of the sea, and washed by its waves. Among the wonders of that place was the temple in which was placed the idol called Somnat. This idol was in the middle of the temple without anything to support it from below, or to suspend it from above. It was held in the highest honour among the Hindus, and whoever beheld it floating in the air was struck with amazement, whether he was a Musulman or an infidel.
It is generally considered that Zakariya was not a traveller, but relied on the works of others, such as Istakhri, Ibn Haukal and others, whom he regularly cites as his authorities.

I don't know, I took a long look at some hi-res pictures and it seems like there is a fair amount of rust on it to me.

I have to wonder if this kind of technology, could be applied in some related way to steel.
The process could revolutionise the big steel constructs that face weathering and corrosion from polution etc.
bridges, towers, etc woud be better preserved this way than painting them every so often, for decades....
Some way to make this happen would make the inventor richer than Gates.
Phosphorus in steel can have beneficial as well as harmful effects. Phosphorus is one of the most potent solid-solution strengtheners of ferrite. The addition of only 0.17% phosphorus increases both the yield and tensile strength of low-carbon sheet steel by about 62 MPa (9 ksi) while also improving the bake hardening response and deep drawability. Because of these properties, rephosphorized high-strength steels are widely used for cold-forming applications. Phosphorus is also used as an additive in steels to improve machining characteristics and atmospheric corrosion resistance. Detrimental effects of phosphorus in steel include various forms of embrittlement which reduce the toughness and ductility. The most familiar example in this category is the classic phenomenon of temper embrittlement in heat-treated low-alloy steels resulting from segregation of phosphorus and other impurities at prior austenite grain boundaries. This form of embrittlement and the contributing role of certain alloying elemen
ts has been a subject of research for several decades.

Exactly.
While everyone else is gaping in awe and wonderment over this "rust free" iron pillar, you had the sense to look at the thing and notice the emporer has no clothes.
Kudos and a star to you for that!

Exactly it is rusted, and there are several spots, that show up even on low res pics , that show significant corrosion. But it is in remarkable condition , given its age. I know ill get slammed for this, but there is no advanced technology involved, just a happenstance of chemistry and location. The trees that supplied the wood (and the phosphorus) grew near the producing foundry, and the climate of its final location produced the unique passivated coating.
It is a wonder of iron foundry work for sure and a testament tothe skill of the craftsmen that made it. Yes it is a casting not a forging, fittings of that size were not physically possible until the late 19th century.

The text is not in any manner connected with the process .
It is proclamation ofr the majesty of King Chandra gupta Vikramaditya who is dedicating the temple to Lord Vishnu and the adoration to Lord Vishnu of the Hindu Pantheon. Lord Vishnu is one of the Hindu Trinity the other two being Lord Shiva and Lord Brahma.
Delhi was never the original location of the Iron Pillar. It was modern day Udayagiri in the State of Madhya Pradesh in India, which was known as Vishnupada giri in ancient times.
Could you tell me how does the praise to Lord Vishnu correlate with a metallurgical process?

what makes me mad is that most of the people in the west think that the west is so techno. superior to these backward people.
that attitude is the farthest from the truth,and if we can manage to get our head outta our arse by realizing we're not the most advanced civilization,maybe we could all work together as one race,and make OUR planet a better place!
just look at the latest shooting in the Sikh temple. the stupid,hate mongering shooter couldn't tell a Sikh temple from a Muslim mosque!!!
well,getting back to my 'the west is the best' attitude, it probably didn't matter to that maniac anyway.
