Introduction
Alloy steels are designated by AISI four-digit numbers. They are more responsive to heat and mechanical treatments than carbon steels. They comprise various types of steels having compositions which exceed the limitations of Va, Cr, Si, Ni, Mo, C and B in the carbon steels.
The following datasheet will provide more details about AISI A5160 alloy steel, which has high ductility, excellent toughness and high tensile-yield ratio.
