📝 Product Description

ASTM A240 TP309S is a high-chromium, high-nickel austenitic stainless steel specifically designed for elevated temperature applications. With approximately 22-24% chromium and 12-15% nickel content, TP309S offers exceptional oxidation resistance and maintains structural integrity at temperatures up to 1100°C intermittently and 1000°C in continuous service. The low carbon content (max 0.08%) minimizes carbide precipitation during welding and thermal cycling.

Our TP309S plates are sourced from premier Chinese mills including TISCO and BAOSTEEL, with full Mill Test Certificates provided. With over 15,000 tons in stock and an in-house processing facility, we deliver custom-cut sizes, surface treatments, and rapid shipment to global destinations via Shanghai and Tianjin ports.

Key Advantage: TP309S outperforms 304 and 310S in cyclic oxidation resistance, making it ideal for furnace components, heat treatment fixtures, and high-temperature processing equipment.

 FAQ

Q: What is the difference between 309S and 310S?

309S has slightly lower chromium (22-24%) compared to 310S (24-26%), offering a cost-effective solution for applications below 1000°C while maintaining excellent oxidation resistance.

Q: Can 309S be used in sulfur-containing environments?

309S performs well in oxidizing atmospheres. For sulfur-rich reducing environments, higher nickel grades like 310S or alloy 800 may be recommended.

Q: Do you provide MTC certificates?

Yes, every shipment includes a Mill Test Certificate showing chemical composition and mechanical properties. Third-party inspection by SGS/BV is also available.

Q: What is the normal lead time for 309S plates?

Common sizes are available from stock within 3-5 days. Custom cutting and non-standard sizes take 7-15 working days after deposit confirmation.
