Introduction
Carbon steels are steels containing carbon as the main alloying element. They are designated by AISI four-digit numbers. They contain 0.4% of silicon and 1.2% of manganese. Small quantities of molybdenum, chromium, nickel, copper, and aluminium are also present in these steels.
The following datasheet will discuss in detail about AISI 1139 carbon steel.
