Grade 25 Chrome steel bearing balls are widely used in precision ball bearings as well as most aerospace, transportation and industrial applications. Chromium (Cr) has a tendency to increase hardness, toughness and wear resistance of steel. Chrome steel is a chrome alloy carbon steel, not a chrome plated steel. Chrome steel balls have excellent surface quality, high hardness and high load bearing capacity as a result of through hardening (Rockwell C 60-67).Chrome steel is approximately 96% iron and capable of being attracted by a magnet. Less expensive case-hardened carbon steel balls are used in consumer goods like drawer slides and casters.
