American Tube Technology, Inc.

merican Tube technology manufactures small diameter tubing in 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. Relative to other alloys, tubing 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!) 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 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. Visit www.astm.org or www.asme.org for more information on widely accepted industry specifications and standards or take a look at our small diameter tubing gauge chart for sizing information. We'd be happy to answer any questions you might have regarding chemical composition and the alloy options at our factory---just call us!

• Series304

04 stainless steel tubing is known for its excellent corrosion and oxidization resistance even at high temperatures, this popular and widely used austenitic stainless steel alloy has excellent cold working properties and strength which makes it an ideal choice for fabricated tube parts. 304 ss tubing is part of the austenitic family of stainless steel and is often referred to as 18-8 stainless steel, it is highly cost-effective relative to other stainless steel tubing alloys. 304 SS tube contains chromium, nickel, and carbon which provides for its durability in low temperatures, corrosion resistance, and ease of fabrication. 304 tubing is used in a broad range of applications from medical, laboratory, industrial and instrumentation. Contact us today to discuss your particular project and stainless steel tubing needs. We provide stainless steel tubing and high nickel alloy tubing in a variety of grades.

17-7 PH stainless steel tubing includes aluminum in the composition and has good corrosion resistance with excellent strength and hardness characteristics. Perhaps its best known quality is the ability to increase hardness and tensile strength via post-cold working heat treating (precipitation hardening), which can increase mechanical strength characteristics of the tubing to levels unachievable by cold working alone. Often, 17-7 PH tubing is used in high strength applications including medical or aerospace.
