Tun Pipes stands out as a top manufacturer and supplier in Naypyidaw, Myanmar, offering high-quality Stainless Steel 409L Pipes that are built to last. These pipes are crafted from low-carbon ferritic stainless steel, ensuring they resist corrosion and perform well over time. With their impressive ability to withstand high-temperature oxidation, 409L pipes are perfect for automotive and industrial exhaust systems. Each pipe is made with precision and meets international quality standards, guaranteeing consistent dimensions and a smooth finish. Across various industries, Tun Pipes’ Stainless Steel 409L Pipes are relied upon for their strength, thermal stability, and resistance to scaling and corrosion in moderately aggressive environments.
Stainless Steel 409L Pipes mainly consist of 10–11.5% chromium and have a very low carbon content (≤0.03%) to reduce carbide precipitation and improve weldability. They also include trace amounts of manganese, silicon, and phosphorus. In terms of mechanical properties, 409L pipes boast a tensile strength of about 450–550 MPa and a yield strength of around 250–350 MPa, along with good elongation. They provide moderate corrosion resistance, excellent oxidation resistance at high temperatures, and are easy to form and weld. These pipes are ideal for applications that involve thermal cycling, vibration, and exposure to mildly corrosive environments, ensuring long-lasting and dependable performance.
