Stainless Steel Balls

Balls have a reflective, mirror-like appearance.

Hardened Heat Treatment—These balls are hardened for increased wear and abrasion resistance.

Tight Tolerance—These balls have a diameter that’s held to a close tolerance.

304 Stainless Steel—From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.

316 Stainless Steel—One of the most corrosion-resistant types of stainless steel, 316 stands up to the harshest chemicals, including bleach, chlorine, and phosphoric acid. It's a step up from 304, which has similar strength and temperature performance. Use it in a variety of marine and chemical-processing applications. It maintains its corrosion resistance in temperatures up to 1500° F.

440C Stainless Steel—440C is one of the hardest types of stainless steel after heat treating. It's often used for bearings and valves. This material maintains its corrosion resistance in temperatures up to 800° F.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
