Introduction
Alloy steels, which are designated by AISI four-digit numbers, are
more susceptible to heat and mechanical treatments than carbon steels.
They comprise different kinds 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 give an overview of AISI 8615 alloy
steel.
