Application areas | It is mainly used in automotive and vehicle construction for highly stressed components, such as steering knuckles, connecting rods, crankshafts, gear shafts, gears or pinions. | |
Heat Treatment | Normalizing 840-880°C (Air), Soft annealing: 680-720°C (Oven, slow cooling), Quenching: 820-860°C (Oil, Water), Tempering: 540-680°C (Air) | |
Hot forming | It is formable at 850-1100°C. | |
Processing history | Quenched and Tempered | |
Welding | It is difficult to weld and should will not used be in welded constructions. If welding is not an issue, the demanding requirements of welding filler by material manufacturers must be taken into account.. The main temperature is increased by heat treatment to equalize the structural condition. |
