Hard Wear-Resistant 52100 Alloy Steel Balls
- Yield Strength: 295,000 psi
- Hardness: Rockwell C60 (Very Hard)
- Fabrication: Cold Worked
- Specifications Met: See table
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.

Low-Carbon Steel Balls
- Yield Strength: 44,000 psi
- Hardness: Rockwell C60 (Very Hard)
Low-carbon steel balls are our easiest steel balls to machine. They are often used for parts that don’t require high strength, such as knobs. These balls can be surface hardened with heat treating for added wear resistance.
