Welded Stainless Steel Tubing

When your application does not require a smooth interior, this tubing is an economical choice. It has a weld bead on the inside.
304 stainless steel has very good corrosion resistance.

- Temperature Range: 304 Stainless Steel: -420° to 1500° F
316 Stainless Steel: -320° to 1500° F - Bending Method: Tube Bender
- Compatible Tube Fittings: See table
General Purpose Aluminum Tubing

- Temperature Range: -450° to 400° F
- Bending Method: Tube Bender
- Compatible Tube Fittings: Flared
This tubing is lightweight with good corrosion resistance and weldability. It has magnesium and silicon added for strength. Tubing is seamless, which provides a smooth interior for unrestricted flow. It can be flared without splitting.
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.
Heat treatable tubes can be surface hardened.
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.

Multipurpose 304 Stainless Steel
From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.
304/304L stainless steel contains less carbon than standard 304 for better weldability.
Seamless round tubes are more corrosion resistant than welded tubes because they don’t have a seam that could potentially introduce impurities.
