Introduction to Steel

Introduction to Steel

In very simple terms, Iron in its solid form assumes a crystalline structure. This means that iron atoms are arranged in a regular repeating pattern called a lattice.

Steel is an alloy of Carbon and Iron.  The video below further explains what steel is, and the effect of carbon on steel.

It is important to recognise that Carbon (and Nitrogen) can enter the crystal structure in the spaces between the iron atoms as they have a very small atomic size. These are called Interstitial Elements of Steel.  Below is an example of a Body Centre Cubic unit cell and is the crystalline form of Pure Iron.
