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.
