Iron versus Steel – What is the difference?


Carbon steel fasteners have high strength and are commonly used for bolting oil and gas pipelines, structural joints, shipbuilding, and automotive products, to name a few. Carbon steel fasteners are often supplied with industrial PTFE coatings for applications which demand strength and corrosion resistance with cost-efficiency.

The difference between iron and steel is simply that iron is an element and steel, in its most basic form, is an alloy of iron and carbon. Some may believe that “wrought iron” is, in some manner, also referring to steel since “wrought” means forged. The terms go back to the origins of ironwork, even before it was done on an industrial scale. The initial refining of iron from ore was, by today’s standards, a crude process, resulting in cast material that was full of defects and inclusions. Making “wrought iron”, the thermomechanical process of forging the cast iron, was the means to further refine and improve iron, making it more useful as a structural material.
