Stainless steel oval tube is a commonly used building material and is widely used. Due to its stable physical and chemical properties, it is suitable for the construction of various engineering buildings.


Part.01, Corrosion Resistance
The component part of the stainless steel oval tube contains chromium. When the stainless steel tube is alloyed with chromium, the type of surface oxide is changed to a surface oxide similar to that formed on pure chromium metal. This tightly adhered chromium-rich oxide protects the surface and prevents further oxidation. This kind of oxide layer is extremely thin, and the natural luster of the pipe surface can be seen through it, giving the pipe a unique surface. Moreover, if the surface layer is damaged, the exposed surface of the pipe will react with the atmosphere to repair itself, re-form a "passivation film", and continue to play a protective role. As a result, the elliptical tube has good corrosion resistance in oxidizing acid, atmosphere, water and other media, and it is also resistant to corrosion by the ocean and corrosive industrial atmosphere.

Part.02, Processing Performance
The stainless steel oval tube has good cold and hot processing performance, and can be produced by various common cold and hot processing techniques. The hot processing temperature range is 900-1180°C. In the solid solution state, the plasticity, toughness and cold workability of the stainless steel oval tube are good. Cold working is easy without special difficulty. Since the elliptical tube is easy to be hardened by cold hardening, when the amount of cold deformation is too large, intermediate annealing treatment must be carried out to facilitate further processing.


Part.03, Mechanical properties
Mechanical properties refer to the mechanical properties exhibited when subjected to various external loads (compression, tension, torsion, bending, impact, alternating stress, etc.) under different environments (medium, humidity, temperature). When testing the mechanical properties of stainless steel elliptical tubes, the bending test is a very important task.
The bending test is to test the mechanical properties of the material under the bending load. In the bending test, the bending angle is 90°, the radius is 3 times the outer diameter of the pipe, and the inner surface of the bending part of the sample must not have wrinkles. Stainless steel pipes have excellent mechanical properties and are very suitable for installation on anti-theft windows, guardrails and shelves.


Part.04, Plasticity
The stainless steel oval tube has strong plasticity. In addition to the commonly used oval tubes and flat oval tubes, various special-shaped tubes can be customized according to customer needs, such as stainless steel single-slot oval tubes, stainless steel double-slot oval tubes, etc., so as to meet the needs of customers' claim.
