Hot rolled AISI 1022 steel bar is a low hardenability carbon steel with low tensile strength ranging between 360-560 MPa. AISI 1022 low carbon steel has Brinell hardness ranging between 100 170 and it is mostly supplied in the black hot rolled condition. Compared to AISI 1020 steel, AISI 1022 steel has a higher content of manganese and carbon.

 

AISI 1022 steel is usually used in the rolled condition. AISI 1022 can be carburized achieving case hardness more than Rc65 with smaller sections. The case hardness reduces with an increase in section size. Hot rolled AISI 1022 low carbon steel has excellent machinability and ductility with reasonable strength.
