Varun Sheets and Plates stands out as a top manufacturer and supplier of Stainless Steel 409 Sheets and Plates in Dubai, UAE. We pride ourselves on delivering durable and cost-effective stainless solutions tailored for both automotive and industrial applications. Stainless Steel 409 is a ferritic stainless steel celebrated for its impressive resistance to exhaust gas corrosion and its good weldability. Our 409 sheets and plates are crafted to meet international standards, guaranteeing consistent quality, precise dimensions, and reliability. We serve various sectors, including automotive, heat exchanger manufacturing, construction, and fabrication, providing dependable materials designed to withstand high temperatures and resist oxidation.
The composition of our Stainless Steel 409 Sheets and Plates includes about 10.5–11.75% Chromium and a low Carbon content (≤0.08%), along with small amounts of Titanium for stabilization. This blend not only boosts corrosion resistance and high-temperature strength but also enhances weldability. The mechanical properties feature a tensile strength ranging from 380 to 585 MPa, a yield strength of around 170 MPa, and an elongation of about 20%. Notably, 409 is magnetic, offers excellent formability, and is highly resistant to both atmospheric and exhaust-related corrosion, making it perfect for welded and fabricated applications.
