AISI 1040 carbon steel is an EN8 steel equivalent that has high carbon content and can be hardened by heat treatment followed by quenching and tempering to achieve 150 to 250 ksi tensile strength. Specifically, it is equivalent to EN8/080M40. It is a medium-strength steel with adequate tensile strength. AISI 1040 carbon steel can be heat treated at 844 to 899°C (1550 to 1650°F) followed by quenching in water and tempering. However, tempering and quenching are commonly not cost-effective for AISI 1040 carbon steel. AISI 1040 carbon steel is used for a number of key industrial applications. It is typically supplied in several forms, including sheets, square and round bars, strips, and plates. It is used in structural applications which require moderate strength. This includes cold-formed bolts and fasteners. Commonly, AISI 1040 carbon steel is used in its case-hardened condition. It is also used in couplings, cold-headed parts, and crankshafts. AISI 1040 carbon steel is an EN8 equivalent steel that contains moderate amounts of carbon and manganese. It is used in applications such as crankshafts, structural elements, and a range of parts that benefit from its heat-treated properties. It can be annealed, normalized, case-hardened, tempered, and welded. This carbon steel type is typically commercially supplied in forms such as sheets, strips, plates, wires, pipes, and many other forms. It possesses beneficial physical properties such as good tensile strength, yield strength, and ductility, which makes it ideal for its many industrial applications. This steel has many different designations depending upon the specific standards.
