One of the reasons why stainless steel is preferred is because they tend to have very high ductility. The ductility of any Oval Stainless Steel Tubing is on the basis of their microstructure, which in turn, is a result of the alloying content of the metal. For instance, if you take the case of alloy grades such as 316 Stainless Steel Oval Tube, the metal has an austenite crystal in its microstructure. The formation and stability of austenite are due to the inclusion of nickel in its alloy.
Austenite has an FCC or a face center cubic microstructure, which makes the alloy of Flat Oval Stainless Steel Tube, ductile as the atoms are packed in a very close knit fashion. Since austenitic stainless steels are ductile, they could be shaped into various forms ranging from a basic round, rectangle, square shape to more complex structures such as the Flat Sided Oval Stainless Steel Tube. Besides being shaped into different forms, it is possible to produce varying Stainless Steel Oval Tube Sizes including dimensions like circumference, wall thickness, and diameter.
Users find several benefits to using a tube that is oval in shape. For instance, the construction of Stainless Steel Elliptical Oval Tubes is stronger, and despite being ductile, they are harder to deform. And because it has very compact construction, most Oval Stainless Steel Tube Suppliers recommend using these tubes in applications that face space constraint issues or applications where compact components are required.
