In addition to hardening iron by adding small amounts of carbon and also some other metals to the molten iron, iron castings or forgings can be heat-treated to take advantage of the various physical properties of the different solid phases of iron. Pure iron reacts readily with oxygen and moisture in the environment and corrodes destructively.

The iron-iron carbide equilibrium diagram is a graphical representation of the phases present in iron and carbon alloys at equilibrium. It shows the relationship between temperature, carbon content, and the phases formed, such as ferrite, cementite, and pearlite. This diagram is essential for understanding the heat treatment processes and control of properties in steel production.

In iron deficiency, there is insufficient iron for iron recycling, while in inflammatory anaemia, increased hepcidin levels result in iron trapping in macrophages. Transferrin is the main iron transport protein; its synthesis is inversely proportional to body iron stores. Hence, levels increase in iron deficiency to facilitate iron absorption.
