where is steel found? what is it used for? and when and where was it discovered?

Question

for my science homework!!

Answer 1

Steel is manufactured by alloying iron and carbon. Stainless steel has a high nickle content.

Wikipedia Excerpt: Perhaps as early as 300 BC, although certainly by AD 200, high quality steel was being produced in southern India also by what Europeans would later call the crucible technique. In this system, high-purity wrought iron, charcoal, and glass were mixed in crucibles and heated until the iron melted and absorbed the carbon. One of the earliest evidence of steel making comes to us from Samanalawewa area in Sri Lanka where thousands of sites were found. (Ref. Juleff, 1996).

Answer 2

Steel is a metal alloy whose major component is iron, with carbon content between 0.02% and 1.7% by weight.

Iron was in limited use long before it became possible to smelt it. The first signs of iron use come from Ancient Egypt and Sumer, where around 4000 BC small items, such as the tips of spears and ornaments, were being fashioned from iron recovered from meteorites

Long steel
Wires
Rail tracks
As girders in building modern tall buildings, bridges

Flat carbon steel
For the inside and outside body of cars, trains
Major appliances

Stainless steel
Cutlery
Rulers
Wrist Watches

Answer 3

steel is iron that has been purified and alloyed with carbon and possibly other elements (stainless steel adds nickel)
