4. 30CrNiMo8 Properties
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.82
5. Forging of DIN 30CrNiMo8 Alloy Steel
Hot forming temperature: 1050-850oC.
6. Heat Treatment
Heat to 650-700oC, cool slowly. This will produce a maximum Brinell hardness of 248.
Harden from a temperature of 830-880oC followed by oil quenching.
Tempering temperature: 540-680oC.
7. Applications of 30CrNiMo8 Round Bar
For permanently stressed components with large cross sections for automotive and mechanical engineering. For economic performance under severe dynamic stress, parts must be designed for optimum strength or toughness.
