Why is the carbon content in steel so important?

Steels, which are alloys of iron and carbon, are one of the most commonly used industrial materials. The amount of carbon that is added to the steel dramatically affects the materials microstructure and mechanical properties. In this video we cover the iron-carbon equilibrium phase diagram and explore how changing the composition of low alloy steels impacts the microstructure by analysing the phases that form.
