These pipes are made from a high-carbon austenitic chromium-nickel alloy, typically featuring 18–20% chromium, 8–10% nickel, and 0.04–0.10% carbon. The higher carbon content boosts strength at elevated temperatures while still offering excellent corrosion resistance. They boast impressive mechanical properties, including a tensile strength of 515–750 MPa, yield strength of 205–275 MPa, and elongation of 35–45%. With outstanding resistance to oxidation, creep, and intergranular corrosion, they are ideal for continuous high-temperature service.
