Mat.No. 1.1157/DIN 40Mn4/AISI 1035
Osaka
Non alloy special sructural steel.
Designation by Standards
| Mat. No. | DIN | EN | AISI |
| 1.1157 | 40Mn4 | - | 1035 |
Chemical Composition (in weight %)
| C | Si | Mn | Cr | Mo | Ni | V | W | Others |
| 0.40 | 0.38 | 0.95 | - | - | - | - | - | - |
Applications
Quenched and subsequently tempered steel for vehicle and engine components, crankshafts for vehicle construction and diesel engines, gear shafts.
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 217.
Normalizing
Normalizing temperature: 850-880oC.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 129-200oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Harden from a temperature of 830-860, 820-850oC followed by oil or water quenching. Hardness after quenching is 53-59 HRC.
Tempering
Tempering temperature: 480-650oC.
Forging
Hot forming temperature: 1100-850oC.
