1020Download 1020 Spec sheet
1020 is one of the very commonly used plain carbon steels. It has a normal carbon content of 0.20% with approximately 0.50% manganese. It is a good combination of strength and ductility and may be hardened or carburized.
1020 steel is used for simple structural application such as cold headed bolts. It is often used in the case hardened condition.
Machinability is good at 65% compared to 1112 carbon steel as 100% baseline.
Formability is good by all conventional methods as the ductility of 1020 is good.
Readily weldable by all of the standard methods.
1020 may be hardened by heating to 1500 – 1600 F and then water quenching. It should then be tempered. More often it is used as case hardened by carburizing. The cost of doing any heat treatment to such a low carbon steel often precludes doing so for the modest return in mechanical properties obtained.
