Introduction
Carbon steels are those that have carbon as the specific alloying element. They 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 sections will give an overview of AISI 1070 carbon steel in detail.
