Features of Stainless Steel Round Tube
Stainless steel round tubes are known for their outstanding corrosion resistance. This is due to the fact that stainless steel round tubes are manufactured from stainless steel materials, the main components of which include iron, chromium and other alloying elements. Of these, the amount of chromium plays a key role in stainless steel.
The presence of chromium forms a protective layer called “oxide film”, which is dense and stable. This oxide film prevents oxygen, water and other corrosive media from coming into direct contact with the stainless steel surface, thus protecting the tube from corrosion.
In addition, the chromium in stainless steel round pipe also has the ability to self-repair. When the stainless steel surface is damaged by mechanical wear or other causes of the oxide film, a new oxide film will quickly re-form, repairing and protecting the pipe.
Stainless steel round tubes are resistant to a wide range of corrosive media such as oxidation, acids and bases, salt water, chemicals and atmospheric conditions. This allows stainless steel round tubes to excel in a wide range of applications, especially in highly corrosive environments such as chemical plants, offshore engineering, and the oil and gas industry.

FAQ
A 321 stainless steel tube refers to a specific type of stainless steel tube that is made from the alloy known as 321 stainless steel. Stainless steel is a versatile and corrosion-resistant material widely used in various industries. The number “321” denotes the composition of the stainless steel alloy, which primarily consists of iron, chromium, and nickel, along with other elements.
The main characteristic of 321 stainless steel is its addition of titanium, which provides enhanced resistance to intergranular corrosion, especially in high-temperature environments. This makes it well-suited for applications where exposure to elevated temperatures is expected, such as in the aerospace, automotive, and chemical processing industries.
Working with reputable stainless steel tube suppliers can ensure that you receive high-quality 321 stainless steel tubes that meet your specifications and performance needs.
The terms “round tube” and “pipe” are often used interchangeably, but there are some subtle differences between them. Here are the key distinctions:
Shape: Round tubes have a circular cross-section, while pipes typically have a cylindrical shape with a round cross-section. The round tube is often characterized by its precise outer diameter (OD) and wall thickness, while pipes are usually specified by their nominal pipe size (NPS) based on the inside diameter (ID).
Manufacturing Process: Round tubes are commonly produced by seamless or welded methods. Seamless round tubes are made from a solid billet of steel that is heated and pierced to form a hollow tube. Welded round tubes are formed by bending a flat strip of steel into a circular shape and then welding the edges together. Pipes, on the other hand, are primarily manufactured through a welded process.
The main differences between 321, 304, and 316 stainless steels lie in their composition and properties. Here’s a breakdown of each grade:
321 Stainless Steel:
Composition: 321 stainless steel contains 17-19% chromium, 9-12% nickel, and 0.08% carbon, along with the addition of titanium (5 times the carbon content) as a stabilizing element.
304 Stainless Steel:
Composition: 304 stainless steel contains 18-20% chromium and 8-10.5% nickel, with a maximum of 0.08% carbon.
316 Stainless Steel:
Composition: 316 stainless steel contains 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, with a maximum of 0.08% carbon.
Consulting with Huaxiao stainless steel suppliers can help ensure you choose the right grade for your specific needs.
There are various processes for processing stainless steel round tubes, and the specific processing method chosen depends on the desired end product shape and size. The following are some common processes for processing stainless steel round tubes:
Cutting: Stainless steel round pipe is cut to the desired length using a cutting tool such as a saw blade, cutter or laser cutter. This is one of the most common processing steps.
Bending: Stainless steel round pipe is bent into the desired shape by applying the appropriate force and heat treatment. The bending process can be done using a manual bending tool, a hydraulic bender or a CNC bender.
Flaring and Shrinking: One end of the stainless steel round pipe is enlarged or reduced using a pipe expander or shrinker to connect to other fittings or to accommodate piping systems of different diameters.
Welding: Stainless steel round tubes can be joined by different welding methods, including TIG (argon arc welding), MIG (gas metal arc welding) and resistance welding. Welding can be used to join the ends of stainless steel round tubes or to join multiple round tubes to form complex structures.
Forming and Cold Working: Using forming tools and cold working machines, stainless steel round tubes can be pressed, stretched or rolled into various shapes to meet specific design requirements.
Polishing and Surface Treatment: The surface quality and finish of stainless steel round tubes can be improved by mechanical polishing, chemical treatment or electrolytic polishing to obtain the desired surface brightness and texture.
Drilling and Processing Holes: Using equipment such as drilling machines, punching machines or laser cutting machines, holes can be drilled or processed in various sizes and shapes in stainless steel round tubes.
It is important to note that different processes may require specialized equipment and techniques, and it is recommended to seek the help of a professional stainless steel tube suppliers when performing complex or precision processing.
