Nial Sheets and Plates is a reputable manufacturer and supplier of Stainless Steel 409 Sheets and Plates, proudly based in Houston, USA. They specialize in providing durable and cost-effective solutions tailored for a variety of industrial and automotive needs. Stainless Steel 409 is a titanium-stabilized, ferritic grade that stands out for its impressive resistance to exhaust gases and atmospheric corrosion, along with good weldability. Nial ensures that their sheets and plates meet international quality standards, catering to industries like automotive, heat exchangers, and construction. With a commitment to timely delivery and precision, Nial offers Stainless Steel 409 products designed for long-lasting performance and structural integrity.
The composition of Stainless Steel 409 Sheets and Plates primarily includes iron and chromium (10.5–11.75%), along with small amounts of carbon, manganese, silicon, and titanium for stabilization. This ferritic alloy is known for its decent oxidation resistance and moderate corrosion resistance, particularly in less aggressive environments. Typically, its mechanical properties feature a tensile strength ranging from 380 to 550 MPa and a yield strength of about 170 MPa, showcasing moderate ductility and excellent formability. The titanium content plays a crucial role in preventing intergranular corrosion, especially after welding or extended exposure to high temperatures.
