Based in Delhi, India, Daksh Sheets and Plates is a well-known producer and supplier of premium stainless steel goods, providing dependable solutions for a variety of industrial uses. Stainless Steel 439 Sheet and Plate is one of our premium products; it is renowned for its exceptional durability, high-temperature stability, and resistance to corrosion. This grade of ferritic stainless steel is especially well-suited for use in industrial machinery, heat exchangers, and automobile exhaust systems. In order to ensure prompt delivery of stainless steel products that satisfy global performance and safety standards, Daksh Sheets and Plates is dedicated to quality, precision engineering, and customer satisfaction.
The ferritic stainless steel alloys known as Stainless Steel 439 Sheets and Plates (UNS S43035) are primarily made of chromium (17–19%), with very little carbon (≤0.03%), trace amounts of titanium (≤0.5%), manganese, silicon, and sulfur. High-temperature performance and corrosion resistance are improved by this composition. The tensile, yield, and elongation strengths of SS 439 are approximately 415–620 MPa, 205 MPa, and 25–35%, respectively. Titanium is a dependable and reasonably priced material for heat-intensive and mildly corrosive environments because it enhances weldability and resistance to intergranular corrosion.
