Carbon Steel 1022

General Characteristics

These grades 1022, 1023, 1025 and 1026 are general purpose low-carbon steels that are easily machined and welded and may be hardened by carburizing and by other surface-hardening methods.

1022 steel is typically used for moderate strength structural applications such as cold formed fasteners and bolts. It is often used in the case hardened condition


1022 steel has good ductility and is readily formed by conventional means.


Weldable by all standard methods. However for heavy sections the use of pre-heat and post- heat is advised.

Heat Treatment

1022 may be hardened by heating to 1500 – 1600 F and water quenching. The product should then be tempered. However for a low carbon steel such as this the improvement in strength from heat treat, quench and temper often are not cost effective in terms of the heat treating cost.


Forge at 2350 to 1800 F.

Hot Working

Hot work at 900 to 200 F.


A full anneal is done at 1700 F with slow furnace cooling. A stress relief anneal may be done at 1000 F.
