What is AISI 1040 Steel?
AISI 1040 steel is a medium-carbon steel alloy that falls under the designation of the American Iron and Steel Institute (AISI) system. The “1040” in the name refers to the approximate carbon content of the steel, which is around 0.40%. This level of carbon content places AISI 1040 in the medium-carbon range, making it suitable for a variety of applications where a balance between strength, hardness, and ductility is required.
