Mat.No. 1.1221/DIN Ck60/AISI 1060
CK60 is one of the higher carbon content (0.60%) steels. It is more difficult to fabricate than the lower carbon grades.
Designation by Standards
| Mat. No. | DIN | EN | AISI |
| 1.1221 | Ck60 | - | 1060 |
Chemical Composition (in weight %)
| C | Si | Mn | Cr | Mo | Ni | V | W | Others |
| 0.61 | max. 0.40 | 0.75 | max. 0.40 | max. 0.10 | max. 0.40 | - | - | (Cr+Mo+Ni) = max. 0.63 |
Applications
Shafts, bushings, connecting rods, nechanical engineering components, agricultural hand tools, large forgings, springs, cold rolled strips.
Physical properties (average values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Soft Annealing
Heat to 650-700oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 241.
Normalizing
Normalizing temperature: 820-850oC.
Hardening
Harden from a temperature of 800-830oC, 810-840oC followed by water or oil quenching.
Tempering
Tempering temperature: 540-680oC.
Mechanical Properties in Normalized Condition
| Diameter (mm) | 0.2 % proof stress (N/mm2) | Tensile strength (N/mm2) | Elongation (%) |
| up to 16 | 380 | 710 | 10 |
| 17-40 | 340 | 670 | 11 |
| 41-100 | 340 | 670 | 11 |
| 101-160 | 310 | 650 | 11 |
| 161-250 | 310 | 650 | 11 |
Mechanical Properties in Quenched and Tempered Condition
| Diameter (mm) | 0.2 % proof stress (N/mm2) | Tensile strength (N/mm2) | Elongation (%) | Reduction (%) | Impact strength (J) |
| up to 16 | 580 | 850-1000 | 11 | 25 | - |
| 17-40 | 520 | 800-950 | 13 | 30 | - |
| 41-100 | 450 | 750-900 | 14 | 35 | - |
| 101-160 | - | - | - | - | - |
| 161-250 | - | - | - | - | - |
Forging
Hot forming temperature: 1100-850oC.
Machinability
Machinability of CK60 and all of the higher carbon steels is relatively poor. CK60 rates at 55 to 60 % that of the AISI 1112 steel which is considered 100% machinable.
Corrosion Resistance
This steel is not corrosion resistant. it will rust unless protected.
Welding
CK60 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 is difficult even in the annealed condition although it may be done by conventional methods but requires greater force than the lower carbon steels. Forms manufactured, Please see the Dimensional Sales Program.
