Isis Metals is a well-respected manufacturer and supplier of Stainless Steel 347 Round Bars and Rods, proudly based in Manila, Philippines. We specialize in high-quality stainless steel products that are engineered for strength, stability, and resistance to corrosion. Our Stainless Steel 347 Round Bars and Rods are crafted to excel in high-temperature and corrosive environments. Using advanced manufacturing processes and top-notch raw materials, they offer outstanding durability, weldability, and oxidation resistance. At Isis Metals, we ensure that every Stainless Steel 347 Round Bar and Rod meets international quality standards, making them perfect for use in the chemical, petrochemical, and engineering sectors.
Stainless Steel 347 Round Bars and Rods are stabilized austenitic stainless steels that contain chromium (17–19%), nickel (9–13%), carbon (≤0.08%), and niobium (10×C–1%) to enhance their resistance to intergranular corrosion. These bars and rods boast a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. They provide excellent oxidation resistance, high-temperature strength, and good formability. Stainless Steel 347 Round Bars and Rods maintain their mechanical integrity even under prolonged heat exposure, making them ideal for environments where strength and corrosion resistance are essential.
