Stainless Steel 409 Pipes mainly consist of chromium (10.5–11.75%), with carbon (≤0.08%), trace amounts of nickel, nitrogen, and a small percentage of titanium (≤0.75%) for stabilization. This unique blend offers solid oxidation and corrosion resistance while ensuring good formability and weldability. The mechanical properties feature a tensile strength ranging from 380 to 550 MPa, a yield strength of about 170 to 240 MPa, and an elongation of 20 to 30%. While they may not be as corrosion-resistant as austenitic grades, 409 pipes provide excellent thermal stability, strength, and scaling resistance at high temperatures, making them perfect for high-heat and moderately corrosive environments.
