CNC-machined Carbon Steel 1040 is a medium-carbon steel that can be heat treated to high strength, with good ductility.
Carbon Steel 1040 is a medium-strength steel with about 0.40% carbon, equivalent to EN8, and can be hardened by quenching and tempering to about 1,030–1,720 MPa tensile strength.
Carbon Steel 1040 is a good option for shafts, axles, gears, and other stressed machine parts that will be heat treated.
