Tight-Tolerance Hardened 440C Stainless Steel
With a diameter that’s held to a close tolerance, this material is hardened for increased wear and abrasion resistance. 440C is one of the hardest types of stainless steel after heat treating. This material maintains its corrosion resistance in temperatures up to 800° F.
Balls have a reflective, mirror-like appearance.

Tight-Tolerance Hard Wear-Resistant 52100 Alloy Steel Balls
- Yield Strength: 295,000 psi
- Hardness: Rockwell C60 (Very Hard)
- Specifications Met: ASTM A295
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. They’re manufactured to ASTM A295 standards for quality and performance.
