Introduction
Steels that have carbon as the key alloying element are called
as carbon steels. They also contain up to 0.4% silicon and 1.2%
manganese. The residual elements such as copper, molybdenum, aluminium,
chromium and nickel are also present in these steels.
The following datasheet will discuss about AISI 1080 carbon steel in
detail.
