These Stainless Steel 409L Pipes mainly consist of iron, with 10.5–11.75% chromium and low carbon content, plus titanium for added stability. This ferritic stainless steel grade is known for its good oxidation and corrosion resistance, especially in mildly corrosive settings. It boasts a tensile strength of about 380 MPa, a yield strength of 170 MPa, and an elongation of 20%. The inclusion of titanium enhances weldability and reduces grain boundary carbide precipitation, ensuring better performance in high-temperature situations.
