CK22 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.
CK22 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.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Heat to 650-700oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 176.
Normalizing temperature: 880-910oC/air.
Harden from a temperature of 860-890oC followed by water quenching.
Tempering temperature: 540-680oC.

Hot forming temperature: 1100-850oC.
Machinability of CK22 steel is quite good, rating a 70% against the standard 1112 steel of 100% machinability.
This steel is not corrosion resistant. it will rust unless protected.
Weldable by all standard methods. However for heavy sections the use of pre-heat and post- heat is advised.
Cold working by conventional methods is readily accomplished. Following severe cold working an anneal may be required.
