CNC-machined Carbon Steel 1015 is a low-carbon steel (about 0.15% carbon) with good ductility and slightly more strength than 1010, suited to light-duty machine parts and formed components.
Carbon Steel 1015 is a low-carbon plain steel with about 0.15% carbon, slightly stronger than 1010 and still very ductile and formable.
Hot-rolled, the material runs about 345–420 MPa tensile and 190–315 MPa yield, with a hardness of about 101–126 HB; cold drawing raises the yield (at least about 285 MPa) at the cost of ductility (about 18% elongation).
Carbon Steel 1015 is commonly used for light-duty machine parts, brackets, and parts needing good formability.
