Introduction
Alloy steels comprise different kinds of steels having compositions which exceed the limitations of Mn, B, Cr, C, Ni, Mo, and Si in carbon steels. They are designated by AISI four-digit numbers. They quickly respond to mechanical and heat treatments.
The following datasheet will discuss in detail about AISI 17-22A alloy steel.
