AISI 1020

AISI 1020 has low hardenability properties and is a low tensile carbon steel with a Brinell hardness of 119 – 235, and a tensile strength of 410-790 MPa. It has high machinability, high strength, high ductility and good weldability. It is normally used in turned and polished or a cold drawn condition. Due to its low carbon content, it is resistant to induction hardening or flame hardening. Due to lack of alloying elements, it will not respond to nitriding. However, carburization is possible in order to obtain case hardness more than Rc65 for smaller sections that reduces with an increase in section size. The core strength will remain the same. Alternatively, carbon nitriding can be performed, offering certain benefits over standard carburizing. AISI 1020 steel can be largely utilized in all industrial sectors in order to enhance weldability or machinability properties. It is used in a variety of applications due to its cold drawn or turned and polished finish property.
