Aditya Stainless, a well-respected manufacturer and supplier located in Kolkata, India, is dedicated to crafting top-notch Stainless Steel 409L Pipes. These pipes are celebrated for their outstanding weldability, resistance to corrosion, and thermal stability. Made from low-carbon, titanium-stabilized ferritic stainless steel, they provide exceptional durability in mildly corrosive and high-temperature settings. Aditya Stainless offers 409L pipes in a variety of sizes and thicknesses, all while adhering to international quality standards. With a strong infrastructure and rigorous quality control, we cater to industries like automotive, power generation, HVAC, and construction, delivering reliable and cost-effective piping solutions designed for long-lasting performance.
Stainless Steel 409L Pipes are composed of chromium (10.5–11.75%) and low carbon (<0.03%), with titanium or niobium added to enhance weldability and resistance to intergranular corrosion. This ferritic stainless steel provides moderate corrosion resistance and good oxidation resistance at higher temperatures. The mechanical properties include a tensile strength ranging from 380–450 MPa, yield strength between 170–240 MPa, and an elongation exceeding 20%. The low carbon content and stabilizing elements ensure excellent formability, ductility, and resistance to thermal fatigue, making SS 409L perfect for applications that experience frequent heating and cooling cycles.
