Steel Balls
 |
Wear-Resistant 52100 Alloy Steel—High carbon and chromium content makes this 52100 alloy steel extremely hard and resistant to wear. It’s also known as chrome steel. Often used as bearings, these balls are hardened for increased abrasion and impact resistance.
Tight-Tolerance Wear-Resistant 52100 Alloy Steel—The diameter of these balls is held to a precise tolerance. They’re made from 52100 alloy steel, also known as chrome steel, which has high levels of carbon and chromium to make them extremely hard and resistant to wear. Often used as bearings, these balls are also hardened to increase their abrasion and impact resistance.
