Bearing Steels
For rolling elements requiring high hardness and fatigue resistance.
Steel & Raw Materials
Bearing Steels
Bearing steels contain about 1% carbon and 1.5% chromium and have a high degree of cleanliness. After hardening they achieve surface hardness above 60 HRC and high rolling-contact fatigue strength.
Besides rings and rolling elements of ball, roller and needle bearings, they are used for wear-resistant rollers, cams and measuring tools.
| Grade | Mat. No. | Typical composition (%) | Typical use |
|---|---|---|---|
| 100Cr6 | 1.3505 | C 0.93–1.05 · Cr 1.35–1.60 | Balls, rings, rollers |
| 100CrMn6 | 1.3520 | C 0.93–1.05 · Mn 1.00–1.20 · Cr 1.40–1.65 | Heavy-section bearing parts |
Values are typical ranges from the relevant standards; exact values are provided with the mill certificate of each delivery.
