304 Stainless Steel Tubing

304 stainless steel tubing (304 Stainless Steel Tubing) is one of the most commonly used types of stainless steel pipes, belonging to the austenitic type. Its main features include excellent corrosion resistance, moderate strength, and excellent formability and weldability. 304 stainless steel tubing exhibits stability in the atmosphere and most neutral media, and is therefore widely used in industries such as food, beverages, medicine, chemicals, construction decoration, etc.

In terms of surface treatment, 304 stainless steel pipes offer a wide range of options:

 

• Polished Finish: The appearance is attractive and suitable for decoration and medical equipment.
• Pickled Surface: The surface is uniformly clean and tidy, and it is commonly used in industrial pipelines.
• Bright annealing (BA Surface): The inner and outer walls are smooth, reducing the resistance of medium flow.

In terms of manufacturing processes:

 

• Seamless Tube: The wall thickness is uniform, with excellent pressure resistance, and is commonly used for the transportation of high-pressure fluids.
• Welded Tube: It offers greater cost advantages and is widely used in low-pressure systems and structural components.

Product advantages

 

• Excellent corrosion resistance: It remains stable in most acidic, alkaline and salt environments, making it particularly suitable for the food and chemical industries.
• Good processing performance: Facilitates cutting, welding, bending and mechanical processing, meeting various structural and process requirements.
• It has a wide range of applications: food processing, beverage transportation, medical equipment, architectural decoration, mechanical manufacturing, etc.
• High cost-performance ratio: Compared to high-nickel materials, 304 stainless steel pipes offer both economic benefits and practicality.
• Beautiful appearance: It can be treated with surface treatments such as mirror polishing and sandblasting, meeting the requirements for decoration and cleanliness.

• Stock preparation and replacement service: For commonly used specifications, we always have sufficient stock in reserve. If customers have urgent replacement needs, we can prioritize the allocation from the inventory to reduce the risk of production halt.

Q1:Can 304 stainless steel pipes be used in the food and beverage industry?

A1:Yes, ✅. 304 stainless steel is known as "food-grade stainless steel." Its smooth, easy-to-clean interior prevents the release of harmful substances, meeting the hygienic requirements for food processing and beverage delivery.

Q2:Do you offer polished and sanitary tubing?

A2:Of course. We can provide the following upon request:

     Mirror Polished Tube

     Brushed Finish Tube

     Sanitary tubing is commonly used in the dairy, pharmaceutical, and beverage industries.

Q3:Will the surface rust?

A3:Under normal conditions, 304 stainless steel pipes offer excellent rust resistance. However, in environments with strong acid, alkali, or high salt spray, 316L or 2205 duplex stainless steel is recommended.
