We are tube experts who have committed themselves to offering the highest quality ERW tubes. Our merchandise comes in all kinds of sizes and shapes to suit varying demands, including oval tubing. There are even specialist finishes available for even greater choice. Not to mention, our fast delivery means you won’t have to wait long in most cases.
Stainless steel oval tubing is regularly employed as a building material. The applications for it are extensive. Because of the stability and chemical and physical properties, the tubes are appropriate for numerous engineering works. What we want to do is discuss the basic features of the oval tube. This should give you a better idea of what kind of utensil you are working with.
Corrosion resistance
Firstly, there is the impressive ability to resist corrosion. The stainless steel alloy includes chromium. It has high corrosion resistance. Including it here means you get a protective oxide on the surface. Such a tightly adhered chromium-rich oxide safeguards the material from oxidation. The oxide layer is also very thin. Through this, it’s possible to see the steel surface’s natural lustre. The steel gains a distinct surface.
Furthermore, if the surface suffers harm, the material will react to the atmosphere to repair itself. It will re-form a passive oxide film and carry on playing a protective part. Due to this, the oval tube has decent corrosion resistance in oxidising water, atmosphere, and acids. Crucially, it can withstand the elements in aggressive industrial settings and marine environments.
Processing performance
Secondly, stainless steel oval tubes have decent hot and cold processing attributes. You can use them with a myriad of operations at different temperatures. The temperature range for hot processing is between 900 and 1180ºC.
In the solid solution state, the cold workability, toughness, and plasticity of the tubes are noteworthy. Cold working is simple and there is no specific difficulty. Since it is easy to cold harden the tubes, when the cold deformation is too big, you must use intermediate annealing treatment. This is to ease extra processing.

Mechanical properties
When we say mechanical properties, we’re on about the features showcased when you expose the tubes to many external loads in different environments. Examples of these are alternating stress, impact, bending, torsion, tension, and compression. Environmental factors include humidity, medium, and temperature.
When testing the mechanical features of these oval tubes, the bending test is vital. It can examine the material’s mechanical features under the bending load. During this test, the bending angle stands at 90º. The radius is three times the tube’s outer diameter. There mustn’t be any winkles on the inner surface of the sample’s bending part.
As for stainless steel tubing, it comes with fantastic mechanical features. Therefore, it is appropriate for many applications.
Plasticity
Finally, stainless steel oval tubing has strong plasticity. What this means is it can withstand deformation without fracturing. That is crucial for working with the material and also ensure is performs excellently after installation.
We have plenty of ERW tubes to spare
At Union Steel Tubes, we have an extensive list of merchandise. It includes ERW tube in different shapes, such as flat oval, round, and square. We specialise in mild steel rather than stainless. It can be a more cost effective option and you can increase the corrosion resistance with galvanisation or other finishes.
If you’re interested in ERW tubes and working with us, please let us know. We can supply them in various lengths thanks to our cutting service.
