1:1020 steel introduction
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. What's more, it will not response to nitriding because its lack of alloy metal element. Core strength will remain as it has been supplied for all the sections.
