Dhruv Metals, a leading manufacturer and supplier based in Hyderabad, India, specializes in high-quality Stainless Steel 347 Bars and Rods, designed to excel in high-temperature and corrosive settings. These products are crafted in accordance with ASTM A276 and A479 standards, featuring a stabilized austenitic stainless steel that includes columbium (niobium) to boost its resistance to intergranular corrosion. Perfect for situations where heat and mechanical stress are constant, Dhruv Metals guarantees top-notch quality, precise dimensions, and prompt delivery, serving industries like petrochemicals, aerospace, power generation, food processing, and high-temperature industrial fabrication.
The Stainless Steel 347 Bars and Rods from Dhruv Metals are composed of 17–19% Chromium, 9–13% Nickel, and Columbium (Nb) + Tantalum, which is up to 10 times the Carbon content, significantly improving their resistance to high-temperature corrosion. The alloy also contains trace amounts of Manganese, Silicon, and Phosphorus. Their mechanical properties boast a tensile strength of at least 515 MPa, yield strength of at least 205 MPa, and an elongation of at least 40%. With a density of 7.9 g/cm³, SS 347 offers remarkable strength, creep resistance, and oxidation resistance, even under extreme temperatures, making it a dependable choice for thermal and corrosive environments.
