With a diameter that’s held to a close tolerance, this material is hardened for increased wear and abrasion resistance.

This material has tighter tolerances than standard 304 stainless steel.

Also known as chrome steel, 52100 is an extremely hard and wear-resistant material. These balls are often used in bearings.

Also known as mild steel, use these low-carbon steel balls in parts that don't require high strength.

Hollow construction reduces weight and allows these balls to float.
