Stainless Steel 409L Pipes consist of 10.5-11.75% chromium, 0.03% carbon, 0.5% nickel, and trace amounts of manganese, silicon, and nitrogen, providing moderate corrosion resistance and superior oxidation resistance at elevated temperatures. Their mechanical characteristics are tensile strength of 380-450 MPa, yield strength of 170 MPa, and hardness of up to 89 HRB, which guarantees structure stability and performance. They have a density of 7.8 g/cm³ and a melting point of around 1530°C, with good thermal conductivity, low thermal expansion, and great strength, which makes them suitable for applications at high temperatures.
Manufactured by welding stainless steel strips, offering cost-effective, corrosion-resistant pipes suitable for automotive exhaust systems and other high-temperature applications.
Produced by fusing stainless steel plates, providing high-strength, oxidation-resistant pipes ideal for exhaust systems and industrial applications with elevated temperatures.
Made using submerged arc welding, offering strong, heat-resistant pipes for large-diameter applications, such as automotive exhaust systems and high-temperature environments.
Manufactured without welding, providing uniform strength and high resistance to oxidation, ideal for use in exhaust systems and other high-temperature, corrosive applications.
Produced by welding stainless steel sections, offering durability and cost-effectiveness for high-temperature and exhaust system applications, with good resistance to oxidation and corrosion.
A square cross-section, providing structural support and heat resistance, ideal for automotive exhaust systems and industrial applications requiring both durability and resistance to oxidation.
Stainless Steel 409L Pipes are utilized extensively in the exhaust systems of automobiles, catalytic converters, mufflers, and heat exchangers where resistance to high temperatures and protection against oxidation is essential. They are also used in petrochemical processes, structural components, and power generation plants, providing toughness in corrosive environments. The pipes can be used in boiler systems, pressure vessels, farm equipment, and industrial furnaces, providing resistance to thermal cycling, mechanical stress, and corrosion. Their high weldability and affordability make them a choice for manufacturing, engineering, and heavy-duty use where long-term performance is needed.
Weston Stainless supplies mill test certificates (MTC) according to EN 10204 3.1/3.2 to keep up with material and mechanical standards. The pipes are carefully packed in wood crates, waterproof cover, or special packaging to avoid damage during shipping and storage. Backed by a solid global supply chain and efficient network of logistics, the company arranges timely shipment, having stringent quality control to provide international industry standards and customer needs.
