General Information

Ovako 832 is a through hardening bearing steel that is mainly used for medium sized bearing rings, but can also be used for machine components that require high tensile strength and high hardness.

• 40 mm maximum wall thickness for through hardening 
• Used for martensitic hardening
• Can be induction hardened
• Good machinability in soft annealed condition
• Machiable in hardened condition using hard-turning techniques (CBN tools)
• Ovako 832 is weldable if pre-heated, otherwise risk of hot-cracking
• Very good dimension stability

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.
