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

TISCO Steel Group (Jiangsu) Co., Limited is your trusted partner and authorized distributor for premium stainless steel products in China. We specialize in supplying high-quality materials directly from the world’s most renowned mills, including TISCO, Tsingshan, BAOSTEEL, and ANSTEEL. This strategic partnership allows us to offer our clients mill-direct pricing, guaranteed material traceability, and consistent supply for projects of any scale.

Our 304L Stainless Steel Sheets are a testament to our commitment to excellence. Grade 304L is the low-carbon variant of the classic 304, engineered to overcome intergranular corrosion issues after welding or exposure to high temperatures. This makes it an ideal choice for applications where welding is extensive or operating conditions involve elevated temperatures. Key advantages include:

  • Excellent Corrosion Resistance: Performs well in a wide range of atmospheric environments and many corrosive media, making it a versatile general-purpose grade.

  • Superior Weldability: The reduced carbon content minimizes the precipitation of carbides at grain boundaries, ensuring maintained corrosion resistance in the weld heat-affected zone.

  • Good Formability and Strength: Easy to fabricate and clean, making it suitable for deep drawing, spinning, and other forming processes.

However, it is slightly less strong at elevated temperatures compared to 304 due to its lower carbon content. It is also not recommended for highly corrosive environments where chloride-induced pitting is a major concern; in such cases, 316L would be a more suitable choice.

Common applications span across industries, including:

  • Food & Beverage Processing Equipment: Tanks, piping, and brewing vessels.

  • Architectural Panels and Trim: For interior and exterior applications in non-coastal areas.

  • Chemical Containers: For storing certain chemicals and solvents.

  • Pharmaceutical Equipment: Where hygiene and cleanability are paramount.

Every sheet we supply is backed by full Mill Test Certification (MTC) and our professional technical support. We ensure your material arrives on time and meets your exact specifications.

FAQ

1. What is the main difference between 304 and 304L stainless steel?
304L has a lower maximum carbon content (0.03% vs. 0.08% in 304), which makes it resistant to sensitization (carbide precipitation) during welding, thus preserving corrosion resistance in welded sections.

2. Do you provide Mill Test Certificates (MTC)?
Yes, we provide a full MTC with every shipment, which includes chemical composition and mechanical properties traceable to the heat number, ensuring compliance with international standards.

3. Can you custom-cut sheets to my size?
Absolutely. We offer precision cutting and slitting services to deliver sheets tailored to your exact dimensions, minimizing your processing time and waste.

4. What surface finishes are available?
We supply 304L sheets in 2B, BA (Bright Annealed), No.4 (Brushed), Hairline (HL), and other finishes upon request.

5. Why is 304L more expensive than 304?
The manufacturing process for low-carbon grades is more controlled, often leading to a slightly higher cost. However, its superior performance in welding applications justifies the price for critical projects.

6. What is the lead time for orders?
For standard sizes and finishes, lead time is typically short. We will provide a precise timeline based on your order volume and specifications.

7. How do you ensure the sheets are not damaged during shipping?
We use export-standard packaging, including waterproof VCI (Volatile Corrosion Inhibitor) paper, sturdy wooden crates, and edge protectors to guarantee perfect condition upon arrival.

8. What is your Minimum Order Quantity (MOQ)?
Our MOQ is typically 1 ton, but we are flexible and can accommodate sample orders for quality verification.

9. Is 304L magnetic?
304L is generally non-magnetic in its annealed state. However, cold working (like cutting or bending) can induce slight magnetism.

10. Can 304L be used in marine environments?
While it offers good general corrosion resistance, 304L is not recommended for prolonged exposure to saltwater or coastal atmospheres due to the risk of pitting and crevice corrosion. 316L is the preferred choice for such applications.

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).

By choosing TISCO Steel Group (Jiangsu) Co., Limited, you will receive professional solutions tailored to your needs.
