With its main office in Hyderabad, India, Daksh Sheets and Plates is a reputable brand in the production and distribution of high-quality metal sheets and plates. Our specialty is SA516 Grade 70 Boiler Sheets and Plates, which are designed to function dependably in high-temperature and high-pressure settings. These carbon steel plates are perfect for demanding applications because of their reputation for accuracy, longevity, and adherence to global standards. Daksh Sheets and Plates, which serves the oil and gas, power generation, and chemical processing industries, is dedicated to providing excellence through technical know-how, quality control, and customer-focused solutions.
Carbon steel plate SA516 Grade 70 is mostly utilized in equipment that is subjected to pressure. Carbon (≤0.27%), manganese (0.85–1.20%), silicon (0.15–0.40%), and phosphorus and sulfur (maximum of 0.035% each) make up its chemical composition. The material has a minimum elongation of 21% in 200 mm gauge length, a minimum yield strength of 260 MPa, and a tensile strength between 485 and 620 MPa. It is appropriate for the fabrication of boilers and pressure vessels due to its exceptional weldability, impact resistance, and crack resistance.
