Ovako 528E and 528Q is a high tensile quench and tempering steel with high wear resistance and good toughness. The grade is mainly used for axis and machine components. Ovako 528Q is produced with the quality class IQ (isotropic quality). This ensures a very low number of elongated sulphide inclusions which will give more isotropic properties. The oxidic cleanliness is high and the steel could therefore meet same high demands as for remelted qualities. Through hardenability corresponding to a bar with approx. Ø75mm (oil quenched) Suitable for flame or induction hardening. Delivered as rolled, soft annealed normalized or quench and tempered. Weldable under certain conditions.
IQ-Steel® is an isotropic quality ultra clean steel optimized for high fatigue strength under multi axial loading.
