304 round tube - Islamabad

Customized, 304 round tube, that is, 304 stainless steel round tube, is a stainless steel material with excellent comprehensive performance.
1. Material and composition
304 stainless steel round tube is mainly composed of chromium (Cr), nickel (Ni) and other elements, of which the chromium content is between 17.019.0% and the nickel content is between 8.011.0%. This chemical composition makes 304 stainless steel round tube extremely corrosion-resistant and has good oxidation resistance.
2. Physical and mechanical properties
Density: The density of 304 stainless steel round tube is 7.93g/cm³, which makes it relatively light in weight and easy to transport and install.
Tensile strength: Its tensile strength is ≥520MPa, showing higher strength characteristics.
Yield strength: Yield strength ≥205N/mm² , which means that it can maintain good shape stability when subjected to external forces.
Elongation: Elongation ≥40%, indicating that 304 stainless steel round tube has good plastic deformation ability when stretched.
Hardness: The hardness value is between HB≤187, HRB≤90, and HV≤200, which provides a guarantee for its wear resistance in various applications.
3. Corrosion resistance
304 stainless steel round tube has excellent stainless corrosion resistance and good intergranular corrosion resistance. In nitric acid below the boiling temperature with a concentration of ≤65%, 304 stainless steel has strong corrosion resistance. In addition, it also has good corrosion resistance to alkaline solutions and most organic and inorganic acids. This excellent corrosion resistance makes 304 stainless steel round tubes in a variety of harsh environments It can maintain stable performance under all conditions.
4. Processing and welding performance
Processing performance: 304 stainless steel round tube has good processing performance and can be formed by cold processing, hot processing and other methods. This makes it more flexible in the manufacturing process.
Welding performance: 304 stainless steel round tube also has good welding performance and is easy to connect with other materials. However, due to its low thermal conductivity and large linear expansion coefficient, special attention should be paid to prevent the generation of residual stress and the occurrence of thermal cracks and precipitation embrittlement during welding.
5. Application field
304 stainless steel round tube has been widely used in many fields due to its excellent comprehensive performance:

Food processing industry: Because 304 stainless steel is not easy to rust and easy to clean, it is suitable for manufacturing Equipment parts that come into contact with food, such as pipes, containers, etc.
Chemical and pharmaceutical industries: In the chemical industry, 304 stainless steel round tubes can be used to transport non-corrosive or weakly corrosive fluid media, such as water and steam. At the same time, in the pharmaceutical industry, its excellent corrosion resistance and easy cleaning properties also make it an ideal material for manufacturing medical equipment and containers.
Building decoration: In the field of construction, 304 stainless steel round tubes can be used for railings, handrails, and other structural parts that need to be beautiful and durable.
Sports equipment manufacturing: Due to its good strength and toughness, 304 stainless steel round tubes can be used to manufacture sports equipment such as bicycle frames and fitness equipment.
VI. Specifications and sizes
304 stainless steel round tubes have various specifications, and common specifications include Φ3~Φ323.85mm and other sizes. Specific specifications and sizes can be customized according to customer needs.

In summary, 304 stainless steel round tubes have become an indispensable material in modern industry with their excellent comprehensive performance, wide application fields, and a variety of specifications and sizes.
