Round Tube & Pipe

Round tube and pipe are extruded products that are widely used for all types of fabrication projects where lightweight and corrosion resistance is a primary concern. The interior is smooth with no seam and is available in an extruded structural or a drawn seamless round tube for higher-precision applications.

Carbon Alloy Aluminum Stainless

Carbon

Grade	Description
A106	Pressure tested. Ideal for high-temperature environments. Suitable for bending, flanging and similar forming operations.
A500 Gr-B	Standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes.
A53	Carbon steel pipe that covers seamless and welded black and hot-dipped galvanized steel pipe. It is used in pressure and mechanical applications and in steam, water, gas, and air lines.
CDS/HFS A519	Good machinability, mechanical tubing great for tubes requiring thicker walls for high pressure and heavy duty applications.
DOM 1020	Low hardenability and low tensile carbon steel. It has high machinability, high strength, high ductility and good weldability.
DOM 1026	Nonresulfurized carbon steel.
SAE J252	Welded and seamless steel pipe, in which the steel cylinder acts as a permanent load carrying member.
SAE J524	Seamless, low carbon steel tubing. Annealed for bending. One of the easiest to bend.

Alloy

Grade	Description
4130	General purpose alloy. Offers good strength and toughness for moderately stressed parts.
4140	Medium carbon steel that is widely used for general purposes. Good hardenability, strength, toughness, wear resistance, and ductility.

Aluminum

Grade	Description
3003	Most widely used of all aluminum alloys. Excellent corrosion resistance and good workability. Added manganese to increase strength 20% more than 1xxx grade.
6061, 6063	Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance.

Stainless

Grade	Description
201	Lower and more stable cost due to the substitution of lower cost manganese and nitrogen. This is a less expensive option, with good resistance to corrosion and tarnishing.
304	Offers resistance to corrosion, has good formability and can be readily welded by all methods. One of the most commonly used grades across the industry.
304L	Extra low carbon avoids harmful carbide precipitation due to welding. Same corrosion resistance as 304 with lower mechanical properties.
316	Better pitting and corrosion resistance than 304, as well as higher strength at elevated temperatures. 316 can be used for valves, marine equipment, pumps, and chemical equipment.
316L	Extra low carbon avoids harmful carbide precipitation due to welding. Same excellent corrosion resistance as 316. It exhibits the same high strength, toughness and workability as 304 alloys.
