Variants
Ovako 248Q is a high cleanliness case hardening steel suitable for demanding powertrain applications. The variant Ovako 248Q is produced in the highest cleanliness level, isotropic quality (IQ), to ensure a minimum of oxidic and sulphidic inclusions. Ovako 248Q is used in diesel injection nozzles.
IQ-Steel®
IQ-Steel® is an isotropic quality ultra clean steel optimized for high fatigue strength under multi axial loading.
