Description
This is one of the higher carbon steels used for high hardness in the fully hardened condition. In such condition the steel is more brittle than the lower carbon steels.
Applications
Quenched and subsequently tempered steel for cold rolled springs strips, wire, forgings, cutting tools, etc.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Soft Annealing
Anneal at 926oC and slow furnace cool.
Hardening
Hardens by cold working and heating and quenching.
Tempering
Temper, after heating and quenching, at 350-700oC. However this steel is most often used in the fully hardened condition (not tempered) of Rockwell C 55 or so.
Forging
Hot forming temperature: 1050-850oC.
Machinability
The machinability of this steel suffers because of the high carbon content. It rates at 50% that of the AISI 1112 steel that is considered the 100% machinable base reference.
Welding
CK75 steel is weldable by all of the welding methods. However with its higher carbon content it is important to use both pre-heat at 150 to 260oC and post-heat at 590 to 650oC practice per an approved welding procedure.
Cold working
Cold working of CK75 is difficult even in the annealed condition. However it may be done by conventional methods but requires more force than for the low carbon steels.
