Khaleed Stainless stands out as a top manufacturer and supplier in Riyadh, Saudi Arabia, offering high-quality Stainless Steel 409 Pipes that are built for performance, durability, and cost-effectiveness. Known for its ferritic properties, SS 409 is celebrated for its impressive resistance to high-temperature oxidation and corrosion in mildly aggressive settings. These pipes are crafted to endure thermal fatigue, making them ideal for automotive exhaust systems, industrial ducting, and other heat-related applications. At Khaleed Stainless, we guarantee that our 409 Pipes adhere to rigorous international quality standards, providing dependable solutions across various industries, including automotive, petrochemical, construction, and power generation.
Stainless Steel 409 Pipes are primarily composed of chromium (10.5–11.75%), featuring low carbon content (≤0.08%) along with trace amounts of manganese, silicon, phosphorus, sulfur, and titanium stabilizers. This unique blend offers exceptional resistance to oxidation, scaling, and heat. In terms of mechanical properties, SS 409 Pipes boast a tensile strength ranging from 380 to 450 MPa, a yield strength of about 170 to 240 MPa, and an elongation of roughly 20%. With a Brinell hardness of 170 HB, these pipes provide moderate strength, excellent formability, and weldability, ensuring reliable performance even under high-temperature conditions and a long service life.
