Introduction
Alloy steels are designated by AISI four-digit numbers and 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 provides more details about AISI 8617H alloy
steel.
