Ovako 825 is a through hardening bearing steel that is mainly used for medium sized bearing rings, but it can also be used for machine components that require high tensile strength, hardness and toughness.
- Through hardenability corresponding to a ring with approximately 30mm wall thickness (≈Ø50mm bar), quenched in oil
- Suitable for martensitic or banitic hardening
- Good machinability in soft annealed condition
- Good dimensional stability
825B - Standard
825T - With a controlled low sulphur content to minimize the number of sulphide inclusions. Reduced carbon content and tighter chemical composition ranges
825Q - Isotropic properties (IQ) and better fatigue strength due to higher cleanliness levels, and a finer size and distribution of non-metallic inclusions
