Iron does not react directly with cold or hot water. It forms a metal oxide when steam is passed over it. When red hot iron reacts with steam it forms iron(II,III) oxide and hydrogen gas is liberated. The reaction is reversible and is shown as follows:

3 F e_{2} + 4 H_{2} O \to F e_{3} O_{4} + 4 H_{2}
