2507 Duplex Stainless Steel Bar by TISCO Steel Group (Jiangsu)

TISCO Steel Group (Jiangsu) Co., Limited is your trusted partner for premium stainless steel solutions. As a leading distributor, we have direct access to top-tier mills including TISCO, Tsingshan, BAOSTEEL, and ANSTEEL, ensuring a reliable supply of high-quality 2507 Duplex Stainless Steel Bars that meet the most stringent international standards.

2507 (UNS S32750) is a super duplex stainless steel that combines the best properties of austenitic and ferritic grades. It offers exceptional strength—approximately twice that of conventional 304 or 316 stainless steels—and outstanding resistance to stress corrosion cracking, pitting, and crevice corrosion, particularly in chloride-rich environments. This makes it the material of choice for demanding applications across various industries. However, it is important to note that 2507 requires careful control during welding and forming due to its specific thermal processing requirements.

You will find 2507 Duplex Steel Bars ideal for:

  • Oil & Gas: Subsea systems, pressure vessels, flow lines.

  • Marine & Shipbuilding: Propeller shafts, pumps, valves in seawater environments.

  • Chemical Processing: Reactors, heat exchangers, piping handling corrosive media.

  • Petrochemical: Equipment exposed to high chloride and acidic conditions.

  • Pollution Control: Flue gas desulfurization systems.

Our advantage lies not just in our material but in our service. We provide expert technical support to help you select the right grade for your project, ensuring optimal performance and cost-efficiency. All our products are backed by full Mill Test Certification (MTC) for guaranteed traceability and quality.

FAQ

  1. What is the difference between 2507 and 2205 duplex steel?
    2507 (Super Duplex) has higher chromium, molybdenum, and nitrogen content than 2205 (Standard Duplex), providing superior strength and corrosion resistance, especially in aggressive environments.

  2. Do your 2507 bars come with material certification?
    Yes, we supply a complete Mill Test Certificate (MTC) with every shipment, ensuring compliance with standards like ASTM A276 and providing full traceability.

  3. Can you provide custom-cut lengths?
    Absolutely. We offer precision cutting services to deliver bars in the exact lengths you require, minimizing your processing time and waste.

  4. What is the minimum order quantity (MOQ)?
    Our standard MOQ is 1 ton, but we are flexible and can accommodate smaller orders for sample testing and evaluation.

  5. What are the machining considerations for 2507?
    2507 is strong and work-hardens rapidly. We recommend using powerful, rigid machinery and positive rake angle tools with appropriate cooling.

  6. Is 2507 stainless steel magnetic?
    Yes, like all duplex grades, 2507 is magnetic due to its ferritic microstructure.

  7. What is the maximum operating temperature for 2507?
    It performs well up to about 300°C (570°F). Prolonged exposure above this can embrittle the material.

  8. How does the price of 2507 compare to 316L?
    2507 is a premium alloy and is significantly more expensive than 316L due to its higher alloy content and superior performance.

  9. What welding procedures are recommended?
    Use matching 2507 filler metal (e.g., ER2594) and low heat input methods like TIG or PAW to maintain the austenite-ferrite balance.

  10. What surface finishes are available?
    We supply black, hot-rolled, turned, polished, or sandblasted finishes. Please inquire for specific options.

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.
