Stainless Steel 321H EFW (Electric Fusion Welded) Pipe is a specialized type of stainless steel pipe that is engineered to meet the specific requirements of high-temperature and corrosive environments. This type of pipe is crafted from Stainless Steel 321H, which is a modification of the popular 321 stainless steel grade. The "H" in 321H stands for high carbon content, which enhances its high-temperature capabilities.

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 321H Composition: Stainless Steel 321H is primarily composed of iron, chromium (around 17-19%), nickel (around 9-12%), and a small amount of titanium (approximately 0.7%) and carbon (0.04-0.10%). This unique composition provides it with excellent resistance to high-temperature environments and corrosion.
2. High-Temperature Performance: Stainless Steel 321H EFW Pipe is specifically designed to withstand elevated temperatures. Its higher carbon content makes it suitable for applications where temperatures reach up to 900°C (1652°F). This makes it a preferred choice for industries like petrochemical, chemical processing, and power generation.
3. Corrosion Resistance: This type of stainless steel pipe offers exceptional corrosion resistance, particularly against intergranular corrosion and general corrosion in acidic environments. It is highly resistant to common corrosive agents such as sulfuric acid and chloride solutions.
4. EFW Welding Process: The EFW welding process involves the fusion of two pipe sections using electric arc welding. This method results in a high-quality, continuous weld with minimal impurities. It is a preferred choice for applications requiring a seamless appearance and high structural integrity.
