CNC-machined Carbon Steel 1010 is a very low-carbon steel with good ductility and formability, low strength, and fairly good machinability. It is suited to cold-headed fasteners and low-stress parts.
Carbon Steel 1010 is a plain carbon steel with about 0.10% carbon, the softest and most ductile of this series.
Typical tensile strength is about 325–365 MPa, yield about 180–305 MPa, and elongation 20–28%, with a hardness of about 95–105 HB. It cold works easily and machines fairly well, especially when cold drawn. It can be quenched and tempered for more strength (about 520 MPa when tempered at 538 °C).
Carbon Steel 1010 is a good option for cold-headed fasteners, bolts, and low-stress components.
