    General Information

    Ovako 245 is an ingot cast case hardening steel with high toughness of the type SAE 3311. It fulfills Ovako internal BQ-Steel demands ensuring a high microscopic and macroscopic cleanliness.

     BQ-Steel® 

    (Bearing Quality) is a bearing quality clean steel optimized for fatigue strength by a strict control of steel cleanliness. BQ-steel is also ideal for new design solutions in a wide array of demanding applications outside the bearing industry that require longer performance and higher loads. The BQ-steel offer is the result of the Ovako clean steel program. Purity of production means that the material has significantly smaller inclusions compared to conventional steel and, as a result, the fatigue strength of the steel is increased dramatically. Use of the material allows components to be manufactured in smaller sizes. The BQ-steel  has for decades been the problem-solver.
