With its main office in Chennai, India, Kunj Sheets and Plates is a well-known producer and supplier of premium stainless steel coils and slitting coils for use in commercial, architectural, and industrial settings. We provide a large selection of stainless steel grades, such as 304, 316, 409, and 430, that are customised to satisfy particular customer needs. Our coils come in a range of thicknesses and widths and are renowned for their accuracy, robustness, and excellent surface finish. With cutting-edge slitting capabilities and a dedication to quality, Kunj provides dependable, corrosion-resistant stainless steel solutions to domestic and international markets for sectors like energy, automotive, food processing, and construction.
Austenitic (304, 316), ferritic (409, 430), and martensitic (410) types are the most common grades of stainless steel coils and slitting coils. With variations in molybdenum, manganese, and carbon for grade-specific performance, their composition normally consists of 16–20% chromium and 8–14% nickel. Depending on the grade, mechanical properties include tensile strength of 450–750 MPa, yield strength of 200–500 MPa, and elongation of 20–40%. These coils are perfect for both structural and ornamental applications in a variety of industries due to their exceptional corrosion resistance, formability, and weldability.
