Ovako 824 Steel
Steel name: Ovako 824
Diagram No.: 5158
Type of diagram: CCT
DIN designation: 100CrMo7
AFNOR designation: 100CD7
EN designation: 100CrMo7
Chemical composition in weight %: 0.92-1.02% C, 0.25-0.40% Si, 0.25-0.40% Mn, max. 0.025% P, max. 0.015% S, 1.65-1.95% Cr, 0.15-0.25% Mo, 0.25% Ni
Steel group: Through hardening steels
Note: Austenitizing temperature: 850 C, holding time: 10 minutes. Ovako 824B is a through hardening bearing steels intended for rolling contact and other high
fatigued applications. In the hardened condition the high hardness, high strength and high cleanliness provides the
steel with the right properties to withstand high cycle, high stress fatigue. 100CrMo7 is mainly used for small and
medium sized bearing components. It is also regularly used for other machine components that require high tensile
strength and high hardness. The hardenability approximately corresponds to a ring with maximum 20 mm wall
thickness. It is suitable for both martensitic and bainitic hardening.
