Smooth-Bore Seamless Stainless Steel Tubing
Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It is stronger than welded tubing and can be flared without splitting.
316 stainless steel offers excellent corrosion resistance.
Tubing that meets ASTM specifications adheres to international standards for dimensions and materials.

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.
Easy-to-Weld 4130 Alloy Steel Round Tubes
- Yield Strength: See table
- Hardness: See table
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: See table
- Fabrication: Seamless
- Specifications Met: See table
Also known as chrome-moly steel, these 4130 alloy steel round tubes have low carbon content for good weldability. They’re often used for roll cages and frames. To increase their wear resistance, you can harden them with heat treating. These tubes have been manufactured to SAE and military standards for quality and performance.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
