1020 S20c HR Carbon Steel Sheet Alloy Structural Steel Plate 1020
1: AISI 1020 steel introduction
AISI 1020 Steel is a low hardenability and low tensile carbon steel. it offers excellent mechanical and chemical properties like high strength ductility, weldability, and high corrosion resistance. 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. it will not respond to nitriding due to lack of alloying elements. However, carburization is possible in order to obtain case hardness more than Rc65 for smaller sections that reduce with an increase in section size.
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 drew or turned and polished finish property.

4: AISI 1020 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.
