TISCO Steel Group (Jiangsu) Co., Limited: Your Trusted Partner for High-Alloy Stainless Steel Pipes

As a distinguished supplier and authorized partner of leading Chinese steel mills including TISCO, Tsingshan, BAOSTEEL, and ANSTEEL, TISCO Steel Group provides unparalleled access to premium-grade stainless steel pipes. Our strategic partnerships ensure that every product we deliver is backed by full mill test certifications (MTC), guaranteed traceability, and the consistent quality that global industries rely on.

Unlocking the Potential of 904L Stainless Steel Pipe

904L (UNS N08904) is a super-austenitic stainless steel specifically engineered for extreme environments. Its key advantage lies in its high Molybdenum (Mo) content (4.5%), and significant Copper (Cu) addition, granting it exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in sulfuric, phosphoric, and acetic acids. This makes it the material of choice for critical applications in:

  • Chemical Processing Equipment: Reactors, pressure vessels, and piping systems.

  • Oil & Gas Industry: Downhole components and pipelines handling sour gases.

  • Pharmaceutical & Food Processing: Where hygiene and corrosion resistance are paramount.

  • Seawater Applications: Heat exchangers and components resistant to chloride-induced corrosion.

While 904L offers superior performance, it is more expensive and requires greater expertise to weld and form than standard 316 stainless steel. This is where our value shines. We don’t just supply material; we provide technical guidance to help you navigate these challenges and implement 904L successfully in your projects.

Why Source from Us?

  • Direct Mill Access: We provide genuine TISCO, Tsingshan, Baosteel, and Ansteel products.

FAQ

  1. What is the main advantage of 904L over 316L stainless steel?
    904L offers significantly higher resistance to pitting and crevice corrosion, especially in environments containing chlorides or sulfuric acid, due to its higher Molybdenum and Copper content.

  2. Do you provide Mill Test Certificates (MTC) with the pipes?
    Yes, we supply a complete MTC with every shipment, which includes chemical composition, mechanical properties, and hydrostatic test results, ensuring full traceability and compliance.

  3. Can you supply 904L pipes according to ASTM A312 and ASME SA312 standards?
    Absolutely. Our 904L pipes are produced to meet ASTM/ASME, EN, JIS, and other international standards as required.

  4. What are the available sizes and schedules?
    We supply a wide range from Sch 5S to Sch XXS, with outer diameters from 1/8″ to 48″. Custom sizes and thicknesses can be discussed.

  5. What is the minimum order quantity (MOQ)?
    Our standard MOQ is 1 ton. However, we are flexible and can accommodate smaller orders for sample testing or specific project needs.

  6. How does your price for 904L pipe compare to 316L?
    904L is a premium alloy with a higher content of costly raw materials like Nickel and Molybdenum, making it more expensive than 316L. We provide the best value by sourcing directly from mills.

  7. What forms do you supply?
    We supply seamless (SMLS) and welded (Welded & EFW) pipes, with various end finishes (plain end, beveled, threaded).

  8. What is the lead time for orders?
    Lead time depends on the size and quantity. Standard specifications can be shipped within 15-20 days. We will provide a precise timeline upon order confirmation.

  9. How are the pipes packaged for export?
    We use VCI rust-proof paper, wooden crates, and reinforced steel straps for secure, export-ready packaging that ensures products arrive in perfect condition.

  10. Can you help with material selection if I’m unsure if 904L is right for my application?
    Yes, our technical sales team has extensive experience. Please share your service environment (temperature, media concentration) and we will recommend the most suitable and cost-effective material.

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).
