Mat.No. 1.1520/DIN C70/AISI 1070
Osaka
Unalloyed carbon steel.Designation by Standards
| Mat. No. | DIN | EN | AISI |
| 1.1520 | C70 | - | 1070 |
Chemical Composition (in weight %)
| C | Si | Mn | Cr | Mo | Ni | V | W | Others |
| 0.70 | 0.20 | 0.25 | - | - | - | - | - | - |
Applications
Quenched and tempered steel for heavy duty parts in machines, vechicles.
Physical properties (average values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Soft Annealing
Heat to 680-710oC, cool slowly. This will produce a maximum Brinell hardness of 183.
Hardening
Harden from a temperature of 790-820oC followed by water. Hardness after quenching is 63-64 HRC.
Tempering
Tempering temperature: 180-300oC.
Forging
Hot forming temperature: 1100-850oC.
