Hastelloy ERW Pipes are primarily made up of high nickel content (up to ~60%), along with molybdenum (15–30%), iron, chromium, cobalt, and trace elements. The exact composition can vary depending on the grade (like C22 or C276), providing remarkable resistance to oxidation and corrosion in challenging environments. These pipes boast a tensile strength of around ~690 MPa, yield strength of about ~283 MPa, and an elongation of ~40%. Their mechanical properties remain stable even at high temperatures. Additionally, Hastelloy ERW Pipes are known for their excellent weldability and formability, making them ideal for critical systems where structural integrity and corrosion resistance are crucial.
