304L Stainless Steel Pipes by TISCO Steel Group (Jiangsu) Co., Limited

TISCO Steel Group (Jiangsu) Co., Limited is an authorized distributor of premium stainless steel from leading mills including TISCO, Tsingshan, BAOSTEEL, and ANSTEEL. Our partnership with these industry giants ensures that every 304L stainless steel pipe we supply meets the highest standards of quality, consistency, and performance, backed by full traceability and Mill Test Certification (MTC).

Why Choose Our 304L Stainless Steel Pipes?
304L (UNS S30403) is a low-carbon variant of the classic 304 stainless steel, specifically designed to minimize carbide precipitation during welding. This grade offers excellent corrosion resistance in a wide range of environments, good formability, and ease of fabrication. It is widely used in applications where welding is required, such as chemical processing equipment, pharmaceutical tubing, food and beverage processing pipelines, and architectural frameworks. While 304L provides superior weldability and intergranular corrosion resistance compared to 304, it may exhibit slightly lower mechanical strength in high-temperature environments.

Our pipes are manufactured to stringent international standards including ASTM A312 and ASTM A269, ensuring reliability in critical applications. We offer a comprehensive range of sizes, schedules, and surface finishes to meet diverse project requirements.

Our Advantages:

  • Direct Mill Supply: We provide genuine TISCO, Tsingshan, BAOSTEEL, and ANSTEEL products with guaranteed quality.

  • Technical Expertise: Our team offers professional guidance on material selection, fabrication, and application optimization.

  • Global Logistics: We support seamless international shipping with export-safe packaging and documentation.

FAQ

1. What is the difference between 304 and 304L stainless steel pipes?
304L has a lower carbon content (max 0.03%) to prevent carbide precipitation during welding, making it ideal for welded structures where corrosion resistance is critical.

2. Do you provide Mill Test Certificates (MTC)?
Yes, all our pipes come with complete MTC documentation traceable to the mill, ensuring compliance with ASTM, EN, and other international standards.

3. Can you customize pipe sizes and lengths?
Yes, we supply custom-cut lengths, OD/WT combinations, and special schedules based on your technical drawings or requirements.

4. What surface finishes are available?
We offer finishes including annealed and pickled, polished (180-grit to mirror), and sandblasted to meet functional or aesthetic needs.

5. What is the lead time for orders?
Standard items are typically shipped within 10-15 days. Customized orders may require additional time based on complexity and volume.

6. Are your pipes suitable for high-temperature applications?
304L is suitable for moderate temperatures but may lose strength at very high temperatures. For extreme conditions, we recommend 321 or 316L.

7. Do you offer competitive pricing for large projects?
Yes, we provide volume-based pricing and dedicated support for large-scale or long-term projects.

8. How do you ensure packaging quality for export?
We use VCI rust-proof paper, wooden crates, and reinforced end caps to protect pipes during transit.

9. What industries commonly use 304L pipes?
Common applications include chemical processing, food and beverage, pharmaceuticals, architecture, and water treatment.

10. Is 304L stainless steel magnetic?
304L is generally non-magnetic in its annealed state but may exhibit slight magnetism after cold working.

Additional Services

We provide value-added services including rough machining, heat treatment, cutting, machining, rolling, welding, and surface treatment to ensure your finished product is delivered ready for finishing. All forgings are rough machined according to your specifications and include Mill Test Reports (MTR), Mechanical and Physical Property Reports, as well as Ultrasonic, X-Ray, and Non-Destructive Testing (NDT) reports (as ordered or specified).
