Description
This is a higher carbon (0.30%) manganese steel in the plain carbon steel alloy family. It provides greater strength than the lower carbon grades while still retaining reasonable ductility.

Applications
CK30 steel is generally used in the quenched and tempered condition for strength. Applications include machinery parts where strength and hardness are requisites.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 200
Density [g/cm3]: 7.85
Thermal conductivity [W/m.K]: 51.2
Specific heat capacity[J/g.K]: 0.486

Soft Annealing
A full anneal is accomplished at 870 to 980oC followed by slow cooling in the furnace. A stress relief anneal may be done at 540oC.

Hardening
Heat treat at 810 to 870oC and water quench, followed by a tempering treatment.

Tempering
Temper, after heat treat and quench, at 320 to 540oC depending upon strength level desired.

Forging
Hot forming temperature: 1050-850oC.

Machinabilty
Machinabilty of CK30 steel is rated at 70 % that of the AISI 1112 steel considered to be 100% machinable as a reference.

Corrosion Resistance
This is a plain carbon steel and will rust unless protected.

Welding
CK30 steel may be welded by all methods. In heavy sections it is advisable to pre-heat at 150 to 260oC and post-heat at 540 to 650oC for welding.

Cold working
Cold working of CK30 steel in the annealed condition may be don by conventional methods. A full or stress relief anneal may be needed after cold working.
