AISI 1020 Steel is low hardenability and low tensile carbon steel carbon steel. And its Brinell hardness of 119 – 235 and tensile strength of 410-790 MPa. It is normally used in turned and polished or cold drawn condition. AISI 1020 steel ( JIS S20C steel) is resistant to induction hardening or flame hardening due to its low carbon content.
