Stainless steel was invented by the Iranians 1,000 years ago, research says

 

Archaeologists have discovered that the first form of "stainless steel" used in modern times was invented about a thousand years ago in the city of "Chahak" in present-day Iran.

The latest issue of the research journal "Journal of Archaeological Science" details the discovery of Raheel Alipur, a British-Iranian expert, and his colleagues, which revealed that the earliest form of stainless steel, which Also called "crucible steel", it was used in ancient Iran to make armor, swords and daggers.

Chahak is a small, unknown town in present-day Iran, but in the eleventh century, about a thousand years ago, it was an industrial city, especially the center of the steel and metal industries.

It should be noted that in the manufacture of modern stainless steel, steel and iron contain a small amount of chromium as well as other minerals. It is a type of steel that does not rust; And for this reason, it has been widely used in various industrial and domestic products for the last two hundred years.

Raheel Alipur, an Iranian-born archaeologist at University College London, described it as evidence of advanced ancient Iran, saying it was the first evidence of "crucible steel" (the earliest form of stainless steel) in the world. He also said that the technique of making stainless steel may have been lost at some point in history, which was rediscovered by Europeans in the 19th century.

If the invention of stainless steel in ancient Iran is compared with another steel made by Muslims, the Damascus Steel, it is estimated that the Muslim civilization of the past may also have specialized in steelmaking.
