Alloy Steels. Usually in Alloy Steels the Pearlite Structure requires less Carbon for it s formation than in ordinary Carbon Steels. Alloying elements change the temperatures at which the structural cahangesd take place. This means that Alloy Steels require different heat treatments to Carbon Steels Alloy additions delay Structural Changes.

Physical Metallurgy of Steel
The steel would not then be referred to as an alloy steel. The definition given is a very broad one and it indicates that a clear concise nice little sub-division scheme to describe all steels is not easily produced.
