303 Stainless Steel Tube

303 stainless steel tube is also known as “18-8” chromium-nickel stainless steel tube and is characterized by its inability to be hardened through heat treatment. In its annealed condition, it typically exhibits non-magnetic properties. 303 stainless steel tube can withstand high temperatures up to 760°C. And 303 stainless steel tubes come with plain, beveled, and threaded ends.

Types of 303 Stainless Steel Tube

Some of the common types of 303 stainless steel tube include:

  1. Seamless Tube: Seamless tubes are manufactured without any welding seams, providing a smooth and continuous surface. They are ideal for high-pressure and critical applications.
  2. Welded Tube: welded tubes are created by joining the edges of a flat strip or plate together through welding, resulting in the formation of a tube. They are available in various diameters and wall thicknesses.
  3. Hollow Bar: Hollow bars are tubes with a larger inside diameter compared to the outside diameter. They are used for applications requiring lightweight and strength.
  4. Capillary Tube: Capillary tubes have a very small diameter and are used in precise applications, such as medical instruments and scientific equipment.
