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.

High carbon and chromium content makes this 52100 alloy steel extremely hard and resistant to wear. It’s also known as chrome steel.

Also known as mild steel, low-carbon steel balls are our easiest steel balls to machine. They are often used for parts that don’t require high strength, such as knobs.
