A reputable brand in the production and distribution of high-end stainless steel products, Daksh Sheets and Plates is based in Delhi, India, and provides creative, high-performing solutions that are suited to industrial needs. The Stainless Steel 321 Coil and Slitting Coil, which are specifically made to function in corrosive and high-temperature environments, are among its premium products. These coils offer exceptional durability, heat resistance, and weldability thanks to their precise engineering and adherence to international standards. Daksh Sheets and Plates continues to provide dependable and reasonably priced stainless steel solutions to a range of industries with a strong emphasis on quality assurance, customer satisfaction, and technical excellence.
Chromium (17–19%), nickel (9–12%), and titanium (up to 0.7%) make up stainless steel 321 coils and slitting coils. By stabilizing the alloy, the titanium addition improves resistance to intergranular corrosion and successfully stops carbide precipitation during welding. These coils have an approximate elongation of 40%, a yield strength of 205 MPa, and a tensile strength of 515 MPa. They are appropriate for welded structures and equipment used in harsh, high-heat environments because they exhibit excellent oxidation and corrosion resistance and perform dependably at elevated temperatures—up to 870°C.
