Principal Design Features
|
|
1022 steel is a slightly higher carbon and manganese content plain carbon steel than 1020. It is used for its somewhat greater strength while still having good ductility.
|
|
|
Applications
|
|
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
|
|
|
Machinability
|
|
Machinability of 1022 steel is quite good, rating a 70% against the standard 1112 steel of 100% machinability.
|
|
|
Forming
|
|
1022 steel has good ductility and is readily formed by conventional means.
|
|
|
Welding
|
|
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.
|
|
|
Forging
|
|
Forge at 2350 to 1800 F.
|
|
|
Hot Working
|
|
Hot work at 900 to 200 F.
|
|
|
Cold Working
|
|
Cold working by conventional methods is readily accomplished. Following severe cold working an anneal may be required.
|
|
|
Annealing
|
|
A full anneal is done at 1700 F with slow furnace cooling. A stress relief anneal may be done at 1000 F.
|
|
|
Tempering
|
|
Temper, after heat treat and quench, at 600 to 1100 F depending upon strength level wanted.
|
|
|
Hardening
|
|
Hardens from cold work or by heat treat, quench and temper.
