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:
- 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.
- 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.
- 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.
- Capillary Tube: Capillary tubes have a very small diameter and are used in precise applications, such as medical instruments and scientific equipment.
Forms of 303 Stainless Steel Tube
Below is the popular forms of 303 stainless steel tube:
- Round Tube: Round tubes have a circular shape, resembling a pipe, and they are frequently utilized in various structural and mechanical applications.
- Square Tube: Square tubes have a square cross-section and are often used in architectural and ornamental applications.
- Rectangular Tube: Rectangular tubes have a rectangular cross-section and are suitable for structural and decorative purposes.
- Coil Tube: Coil tubes are formed in a coiled shape and are commonly used in heat exchangers and refrigeration systems.
