Introduction

Carbon is the main alloying element found in carbon steels. Chromium, nickel, copper, molybdenum, and aluminium are present in small quantities. These steels contain 0.4% of silicon and 1.2% of manganese.

AISI 1117 carbon steel contains more manganese than other lower-carbon steels in order to ensure good hardenability.

The following datasheet will discuss in detail about AISI 1117 carbon steel.
