According to AISI (American Iron and Steel Institute), the best metal for forging is low- or medium-carbon steel.

The forging tool can sometimes be specific to the forging process, but a commonly known term for the tool is “Forging Die”.

There are various types of forging: Hot, Cold, Open-die, Closed-die, Press, Upset, and Roll forging. The open-die and closed-die forging are included under the drop forging manufacturing process.

The most common materials used for forging are aluminium-based alloy steel, Carbon Steel, Nickel Based Alloys, Stainless Steel, and tool steel.

Water is generally used for either quenching after the process or cooling during the process is used in forging.
