Our Grade 310S stainless steel pipe, also known by its material number 1.4845, represents the ultimate solution for high-temperature applications. Manufactured in strict compliance with international standards including EN, DIN, GB, ASTM, and JIS, this pipe is supplied in the standard 6-meter length, ensuring reliability and performance for the most demanding industrial environments. This austenitic chromium-nickel stainless steel is specifically designed to offer exceptional oxidation resistance, superior creep strength, and excellent corrosion resistance, making it an indispensable material for critical processes across various sectors.
Grade 310S is the low-carbon version of the 310 alloy, which enhances its weldability and resistance to intergranular corrosion. Whether you are involved in furnace engineering, chemical processing, or power generation, our 310S/1.4845 stainless steel pipe provides the durability and longevity required to ensure operational integrity under extreme thermal and corrosive conditions.
Key Features and Benefits
-
Exceptional High-Temperature Performance: Designed to withstand temperatures up to 1100°C (2010°F) continuously, and even higher in intermittent service. Its high chromium and nickel content forms a stable, protective oxide layer that prevents scaling and resists cyclic oxidation.
-
Superior Corrosion Resistance: Offers excellent resistance to oxidation, sulfidation, and other forms of hot corrosion. It also performs well in many aqueous environments, resisting corrosion from various chemicals.
-
Low Carbon Content (0.08% max): The 'S' in 310S stands for 'stable'. The reduced carbon content minimizes carbide precipitation during welding and exposure to high temperatures, thereby preventing intergranular corrosion and preserving the material's toughness.
-
Outstanding Creep Strength: Maintains its mechanical properties under high stress over long periods at elevated temperatures, which is critical for components in boilers, reformers, and radiant tubes.
-
Excellent Formability and Weldability: Can be readily fabricated and welded using all standard techniques, allowing for the construction of complex high-temperature systems.
