Located in Delhi, India, Vipul Sheets and Plates is a top producer and supplier of high-grade stainless steel 409 coils and slitting coils. Stainless Steel 409 is an affordable ferritic stainless steel grade that is frequently utilised in industrial and automotive applications. It is well-known for its exceptional resistance to high-temperature oxidation and corrosion. Vipul Sheets and Plates serves a variety of industries, including heat exchangers, construction, and automotive exhaust systems, by guaranteeing products with exceptional mechanical qualities, surface finish, and dimensional accuracy. With an emphasis on accuracy, prompt delivery, and client satisfaction, the business provides customised solutions to satisfy a range of industrial demands.
The main component of stainless steel 409 coils and slitting coils is chromium (10.5–11.75%), with stabilising trace amounts of nickel, carbon (≤0.08%), manganese, silicon, and titanium. This ferritic stainless steel has good formability and a moderate resistance to corrosion. Its yield strength is between 170 and 240 MPa, its tensile strength is between 380 and 450 MPa, and its elongation is about 20%. At temperatures as high as 675°C, 409 resists scaling and retains mechanical integrity under thermal stress. Because of these characteristics, it is an affordable option for situations requiring welding and forming that are heat-resistant and mildly corrosive.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Stainless Steel 321 Coils and Slitting Coils offer exceptional resistance to high temperatures and oxidation, making them ideal for use in heat exchangers, aerospace components, and chemical processing industries. The addition of titanium stabilizes the alloy, preventing carbide precipitation and ensuring excellent weldability. These coils also provide strong resistance to intergranular corrosion, pitting, and crevice corrosion. With high tensile and yield strength, they maintain structural integrity under extreme conditions. Their durability, combined with excellent formability and resistance to scaling, makes them a reliable choice for demanding industrial applications.
Yes, we offer custom sizes for Stainless Steel 321 Coils to meet specific project needs. Our team at Vipul Sheets and Plates is dedicated to providing tailored solutions for all your requirements. For more details, contact us at sales@vipulsheetsplates.com.
Because of their affordability and heat resistance, stainless steel 409 coils and slitting coils are widely used in the automotive industry, particularly for the production of exhaust systems, mufflers, catalytic converters, and tailpipes. They are employed in construction for structural support, roofing, and cladding in mildly corrosive conditions. Additionally, the material can be used for fuel filters, heat exchanger tubing, and industrial ventilation systems. 409 is prized for its weldability and resilience to heat and vibration in railway and agricultural applications. It is perfect for large-scale, high-temperature service applications because of its strength, resistance to corrosion, and affordability.
