Alloy steels contain different kinds of steels exceeding the composition limits of Mn, C, Mo, Si, Ni, Va, and B set for the carbon steels. They are designated by AISI four-digit numbers. The first two digits represent the main alloying elements, and the last two digits represent the carbon content present in the alloy in hundredth of a percent. They react more quickly to mechanical and heat treatments than carbon steels.

The datasheet given below provides more details about AISI E9310 alloy steel.
