Description
C22 is one of the very commonly used plain carbon steels. It has a nominal carbon content of 0.22% with approximately 0.55% manganese. It is a good combination of strength and ductility and may be hardened or carburized.
Applications
C22 steel is used for simple structural application such as cold headed 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]: 7.70
Thermal conductivity [W/m.K]: 51.9
Electric resistivity [Ohm mm2/m]: 0.11
Specific heat capacity[J/g.K]: 0.46
Soft Annealing
Heat to 870-980oC, cool slowly. This will produce a minimum tensile strength of 450 Mpa.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 540oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Harden from a temperature of 820-870oC followed by water quenching.
Tempering
Tempering temperature: Please ask.
Forging
Hot forming temperature: 1200-950oC.
Machinability
Machinability is good at 65% compared to 1112 carbon steel as 100% baseline.
Corrosion Resistance
Not corrosion resistant. The steel will rust unless protected.
Welding
Readily weldable by all of the standard methods.
Cold working
C22 steel is readily cold worked by all conventional methods. A stress relief anneal may be needed after extensive cold work.
