We Supply Stainless Steel EFW Pipes in Grades in Specification ASME SA / ASTM A269, A312, A213 and Grades 202, 304, 304L, 304H, 304LN, 309s, 310s, 316, 316L, 316H, 316Ti, 316LN, 317L, 321, 321H, 347, 347H, 904L, 254 SMO , 6MO , 6 MOLY, UNS S31254 etc. The grade indicates the testing methods required for a given application.


1. Stainless Steel 321 Composition: Stainless Steel 321 is primarily composed of iron, with significant amounts of chromium, nickel, and a small amount of titanium. The addition of titanium stabilizes the alloy against carbide precipitation, which occurs at high temperatures, making it suitable for high-temperature applications.

2. High-Temperature Resistance: Stainless Steel 321 offers excellent resistance to high temperatures, making it suitable for applications where exposure to heat is common. It retains its mechanical properties and corrosion resistance even at temperatures up to 900°C (1652°F).

3. Corrosion Resistance: This stainless steel alloy provides outstanding corrosion resistance in various environments, including acidic, alkaline, and chloride-rich settings. It is particularly resistant to intergranular corrosion due to its titanium content.

4. Weldability: Stainless Steel 321 is readily weldable using standard welding techniques, and its EFW pipes are created through the electric fusion welding process. This process ensures a strong and reliable bond between the pipe sections.

5. Versatility: Stainless Steel 321 EFW Pipe is versatile and finds applications in industries such as chemical processing, petrochemical, aerospace, food processing, and pharmaceuticals. It is often used for manufacturing heat exchangers, pressure vessels, and exhaust systems.

6. Durability and Longevity: Thanks to its corrosion resistance and high-temperature performance, Stainless Steel 321 EFW Pipe has a long service life, reducing maintenance and replacement costs.

7. Sizes and Specifications: These pipes come in various sizes and thicknesses, allowing them to be tailored to specific project requirements. Specifications may vary depending on the manufacturer and customer needs.

8. Compliance with Standards: Stainless Steel 321 EFW Pipe typically conforms to industry standards and specifications, ensuring quality and consistency in its performance.
