Carbon steels are steels that contain only carbon as their major alloying element. These steels also contain small quantities of copper, nickel, molybdenum, aluminium and chromium. Traces of 0.4% silicon and 1.2% manganese can also be found in these steels.
The following datasheet provides an overview of AISI 1021 carbon steel.
The chemical composition of AISI 1021 carbon steel is outlined in the following table.
The following table shows the physical properties of AISI 1021 carbon steel.
The mechanical properties of cold drawn AISI 1021 carbon steel are displayed in the following table.
|Bulk modulus (typical for steel)
|Shear modulus (typical for steel)
|Elongation at break (In 50 mm)
|Reduction of area
|Hardness, Knoop (converted from Brinell hardness)
|Hardness, Rockwell B (converted from Brinell hardness)
|Hardness, Vickers (converted from Brinell hardness)
|Machinability (based on AISI 1212 steel as 100 machinability. The machinability of Group I bar, rod, and wire products can be improved by cold drawing.)
