Small Diameter Stainless Steel Tubing

American Tube Technology is a small diameter stainless steel tube manufacturer for a variety of alloys that can be used in numerous demanding applications, but none more than in 300 series stainless. Many of our customers rely on 300 series stainless steel, due to its ease of forming and comparatively low cost. Small diameter stainless steel tubing coil, relative to other alloys, can be welded and drawn to size efficiently in this series of stainless steel. We typically work with the following austenitic grades (but frequently produce tubing with other grades on request---just ask!)

More Information

Low carbon versions of our alloys are also available. "L-grade" 300 series stainless steel tubing exhibits improved corrosion resistance along the weld zone and reduced carbon precipitation in welding applications like brazing. The end result is stronger joints in assemblies. Combined with our T.I.G. welded and drawn production process, corrosion resistance in our 300 "L" series tubing is generally uniform throughout the tube with reduced susceptibility to intergranular corrosion.

American Tube Technology also produces small diameter tubing in a range of other alloys and grades upon request. The flexibility of our equipment and the knowledge of our staff puts us in a prime position to help with special requests. Tempers ranging from annealed to full hard are available. Our product is produced domestically at our Colorado mill, and we can offer DFARS compliant material upon request.

We'd be happy to answer any questions you might have regarding chemical composition and the alloy options at our factory---just call us!
