Lecong Stainless is a reputable manufacturer and supplier based in Da Nang, Vietnam, known for providing top-notch Stainless Steel 409 Pipes that blend strength, durability, and affordability. This ferritic stainless steel grade is prized for its impressive corrosion resistance, outstanding oxidation resistance at high temperatures, and excellent weldability. These pipes are crafted to excel in tough industrial and structural settings, particularly where heat and moderate corrosion resistance are essential. With state-of-the-art manufacturing facilities and rigorous quality control measures, Lecong Stainless guarantees that their Stainless Steel 409 Pipes meet international standards, ensuring reliable performance both in Vietnam and around the globe.
The composition of Stainless Steel 409 Pipes primarily includes iron, chromium (10.5–11.75%), manganese, silicon, and low carbon, with titanium occasionally added for stabilization. This blend enhances weldability, toughness, and scaling resistance at higher temperatures. Their mechanical properties feature a tensile strength ranging from 380 to 450 MPa, a yield strength of about 170 to 240 MPa, and good elongation for formability. The ferritic microstructure contributes to thermal stability, precise dimensions, and long-lasting durability. While their corrosion resistance may not match that of austenitic stainless steels, Stainless Steel 409 Pipes perform admirably in moderately corrosive and oxidizing environments, making them a cost-effective and dependable option for various piping applications.
