Ovako 100CrMnSi4-4 831B Steel, Spheroidize annealing
Categories:	Metal; Ferrous Metal; Alloy Steel; Low Alloy Steel; Carbon Steel; High Carbon Steel
Material Notes:	General Information: Ovako 831 is a through hardening bearing steel that is mainly used for medium sized martensitic hardened bearing components, but it can also be used for machine components that require high tensile strength and high hardness. Ovako 831 has a controlled Ni and Mo content for enhanced and consistent hardenability. 831B - Bearing quality (BQ) variant Through hardenability corresponding to a ring with approximately 20mm wall thickness (~Ø35mm bar) Can be induction or flame hardened Good machinability in soft annealed condition Very good dimensional 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 BQsteel 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. Information provided by Ovako
