Smoother and straighter than standard 440C stainless steel rods, these rods are made to tight tolerances with centerless grinding. They’re used to create cylindrical parts where a consistent diameter is key, such as bearings and drive shafts. The high carbon content in 440C stainless steel helps it withstand abrasion and wear better than any other stainless steel. Like tool steel, it can be heat treated to become extremely hard. It also maintains its corrosion resistance in temperatures up to 800° F. However, it’s more likely to break than bend from impacts.

One of the hardest types of stainless steel after heat treating, 440C offers excellent wear and abrasion resistance. It’s often used for bearings, valves, and knife blades. 440C has even more carbon than 440A, making it harder but less tough. That means 440C is more likely to break rather than bend when absorbing impact. This material maintains its corrosion resistance in temperatures up to 800° F.

Precision ground to our tightest tolerance and hardened, these rods come ready to use—no additional heat treatment required. They offer high strength and exceptional abrasion resistance. They're often used for precision shafts, pins, and linear motion components. 440C stainless steel maintains its corrosion resistance in temperatures up to 800° F.

The best choice for high-performance bearings and valves, these 440C stainless steel balls are among the strongest, hardest, and most wear-resistant we offer. They’re passivated to wash away surface particles that cause rust, and they’re polished to a mirror-like finish that contaminants can’t stick to. The result is balls that stay smooth and stand the test of time—even at temperatures up to 800° F. They’re made to strict ISO 3290 standards for roundness and surface quality.

These balls are magnetic, so you can use them in separators, sensors, and automated handling systems that use magnetic pickup or positioning.
