Introduction
Steels containing carbon as the main alloying element are collectively known as carbon steels. They contain 0.4% silicon and 1.2% manganese. Residual elements such as molybdenum, chromium, aluminium, copper, and nickel are present in traces. They are designated by AISI four-digit numbers.
The following datasheet gives an overview of AISI 1335 carbon steel.
