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. This steel is manufactured to ASTM, SAE, or EN standards for quality and performance.
DOM (drawn over mandrel) welded tubes are stronger than ERW (electric resistance welded) tubes.Tubes that are stress relieved minimize warping during machining.
