Question

Where did steel/metal come from? Who discovered it? How do we make it?

I have been wondering who made/discovered stell/metal. I really hope you could answer this. I'll give Best Answer for the first one who answers this question., if it is good.

Answer 1

The first metals worked by man were gold, copper, and bronze (a copper-tin alloy).  These metals can be found in relatively pure form (no smelting required) near the surface of the earth, making their discovery easy.  Also, because of their ductility, softness, and low melting temperature, these metals are easy to work without sophisticated tools.  Bronze and gold were worked in the Middle East and North Africa by at least 3000 BC.  

Aside from iron meteorites (which were formed into jewelery by the ancient Egyptians as early as 4000 BC), iron is found only as ores, not as pure metal, in the Earth's crust.  Iron's hardness and high melting point also make it difficult to work.  However, its hardness and ability to hold a much sharper edge than the Bronze-age metals, gave iron-working civilizations a huge military advantage over their neighbors.  The Illiad, Homer's early Iron-age epic, refers constantly to "difficultly-worked iron," emphasizing its importance to highly militarized cultures like the ancient Greeks.  

Several civilizations practiced iron working around 1300 BC, including the Hittites, West Africans around the city of Meroe, and several cities in northeast India.  However, since Iron working was difficult, and a closely guarded secret by the cultures that developed it, it took half a millenium for iron working to spread throughout Europe and Asia.  

Steel (iron with trace amounts of carbon or other impurities) was used to make the best weaponry by the time of the Roman empire, though the Romans probably imported the steel from the Middle East rather than manufacturing it themselves.  Steel came into its own in the middle ages, with China, Japan, and several western European countries producing steel of exceptional quality.  

Stainless steel (typically an iron-nickel-chromium alloy) was discovered in 1821, but not widely commercialized until the turn of the 20th century.

Answer 2

Iron was discovered in pre-history. It was made by burning coal and iron ore so in places where you could get these iron was made.

It was also used by aborigines where it was collected in the desert where it had arrived by falling from the sky in the form meteorites.

Steel was discovered many hundreds of years ago but until the Bessemer process was invented by Henry Bessemer in 1855 it was not easy to make in any quantity or quality.
