Who invented steel and what year?
13th century BC – The earliest evidence of steel production can be traced back to early blacksmiths in the 13th century who discovered that iron become harder, stronger and more durable when carbon was introduced after being left in coal furnaces.
How was steel originally made?
One of the earliest forms of steel, blister steel, began production in Germany and England in the 17th century and was produced by increasing the carbon content in molten pig iron using a process known as cementation. In this process, bars of wrought iron were layered with powdered charcoal in stone boxes and heated.
When was steel first used?
The earliest known production of steel is seen in pieces of ironware excavated from an archaeological site in Anatolia (Kaman-Kalehöyük) and are nearly 4,000 years old, dating from 1800 BC.

Why was steel invented?
Steel was invented because iron, while very useful in its own right, did not perform as well in various material properties as it could if properly alloyed. Production of steel is largely about controlling the carbon content of the alloy.
