One 1-3/4" Inch Chrome Steel Bearing Ball

One 1-3/4" Inch Chrome Steel Bearing Ball

• Precision grade 25 bearing balls
• Hardness: Rockwell C 60-67
• 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.
