Iron vs Steel: What''s the Difference?

 · You don''t need to consume steel as part of your diet. The primary difference between iron and steel is that the former is a metal, whereas the latter is an alloy. Iron is simply a metal element that occurs naturally on Earth. In comparison, steel is a man-made alloy that''s made by mixing iron and carbon together.

What is Structural Steel? Composition and Applications

 · Although iron is often believed to be strong and hard, raw iron ore is so soft that it can be cut with a knife and some muscle. Iron-based alloys get their strength from the addition of carbon. An iron-carbon alloy is generally produced by combining coke with iron ore and applying heat until the coke ignites.

What is Smelting? (with pictures)

As the ore precipitates out and gathers together, density changes in the composition of the material will cause it to form layers, allowing the operator to skim off the desirable ore. After the smelting is complete, people can take out the byproducts and discard them, although sometimes there are uses for them, such as combining them in aggregate concrete mixtures.
