|Material Grade||C 1020|
C-1020 is a low hardenability and low tensile carbon steel with Brinell hardness of 119-235 and 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 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. Core strength will remain as it has been supplied for all the sections. Alternatively, carbon nitriding can be performed, offering certain benefits over standard carburizing. C1020 offers better machinability than the normal low carbon commercial alternative of A36. A low carbon, general purpose, special quality machinery steel, suitable for ordinary hammer forging and case hardening. Readily weldable.
- In the cold drawn or turned and polished condition, AISI 1020 steel has high machinability.
- As per recommendations of machine manufacturers, AISI 1020 steel can be used for drilling, turning, milling and tapping operations using suitable feeds, tool type and speeds.
- AISI 1020 can be welded by performing the most common welding processes.
- In the cold drawn or turned and polished condition, it has better weldability.
