Khaleed Stainless is a reputable manufacturer and supplier based in Riyadh, Saudi Arabia, specializing in high-quality Stainless Steel 409 Sheets and Plates. These products are crafted for durability, performance, and cost-effectiveness. As a ferritic stainless steel, SS 409 is known for its impressive resistance to oxidation, heat, and corrosion, especially in mildly aggressive environments. While aesthetics may not be the main focus, these sheets and plates are essential where strength, longevity, and affordability matter most. With meticulous manufacturing standards, Khaleed Stainless guarantees that its 409 Sheets and Plates cater to the varied needs of the automotive, exhaust systems, construction, and industrial sectors.
Stainless Steel 409 Sheets and Plates mainly consist of chromium (10.5–11.75%), carbon (≤0.08%), manganese, silicon, phosphorus, sulfur, and small amounts of titanium for stabilization. This blend boosts their corrosion resistance and oxidation tolerance at high temperatures. In terms of mechanical properties, SS 409 showcases a tensile strength of about 380–450 MPa, a yield strength ranging from 170–240 MPa, and an elongation of 20%. With a Brinell hardness of roughly 170 HB, they provide moderate toughness, good weldability, and thermal stability, making them ideal for heat-intensive and structurally demanding industrial applications.
