Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and conduit.

Made from alloy steel, also known as chrome-moly steel, these tubes resist fracturing from repeated stress. They’re used for a wide range of parts, including cylinders, rollers, and frames.

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.
