CK35 steel has a higher (0.35%) carbon content for greater strength than the lower carbon alloys. It is hardenable by heat treatment, quench and tempering to develop 150 to 250 ksi tensile strength.
Component parts for automobile industry, e.g., shafts, forgings, flanges, bushings, crankshafts, connecting rods and parts for the machine building industry.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.86
Heat to 650-700oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 226.
Normalizing temperature: 880-910oC.
Harden from a temperature of 805-845oC followed by oil or water quenching.
Tempering from the quenched condition may be done at 550-660oC depending upon the strength desired.

Hot forming temperature: 1100-850oC.
Machinability is good, rated at 60% that of the AISI 1112 alloy used as a 100% machining rated steel.
This is a steel alloy and will rust if not protected. it is not corrosion resistant.
CK35 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.
In the annealed state the CK35 alloy is readily cold worked by conventional methods.
