The distribution of the alloying elements in an alloy steel depends on its composition. Many complex interactions can occur and, as the number and amount of alloying elements are increased, the complexity of the interactions also increases. However, there are basic trends in the distribution of the alloying elements which can be observed and which are listed in Table for annealed alloy steels at room temperature.
