Chrome steel balls are hardened and cannot be drilled or tapped
Chrome steel is approximately 96% iron and fully magnetic
Chrome steel balls have excellent surface quality, high hardness and high load bearing capacity as a result of through hardening
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.
