Multipurpose Low-Carbon Steel Round Tubes
 |
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.
Heat Treatable—Heat treatable tubes can be surface hardened.

Multipurpose Low-Carbon Steel Rectangular Tubes
 |
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. These tubes are often fabricated into parts that don’t require high strength, such as frames, supports, and raceways. To increase their wear resistance, you can surface harden them with heat treating.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
