The diameter on these balls is held to a precise tolerance.

Easier to machine than 52100 alloy steel rods, these extremely hard and wear-resistant tubes are often used to create bearings, bushings, and other cylindrical parts that are under constant stress. They’re also known as chrome steel.

Also known as mild steel, use these low-carbon steel balls in parts that don't require high strength.

With a diameter that’s held to a close tolerance, this material is hardened for increased wear and abrasion resistance.

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications.

Widely used as bearings and in valves, 2017 aluminum is a durable, lightweight material.

This S2 tool steel has been hardened for excellent strength and impact resistance. It has a tough core that resists breaking under shock loads.
