Hastelloy EFW Pipes are made from high-performance nickel-based alloys like Hastelloy C276, C22, or B2. The composition typically includes Nickel (~58%), Molybdenum (up to 30%), Chromium, Iron, and trace elements such as Cobalt and Tungsten. These pipes are known for their exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. They boast tensile strengths between 690–760 MPa and yield strengths of 280–350 MPa, with elongation exceeding 40%. With excellent weldability, structural integrity, and thermal stability, Hastelloy EFW Pipes are perfect for critical and high-temperature applications.
