Aung Metals, a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, is known for its top-notch Stainless Steel 347H Square Bars and Rods. These bars are specially designed to provide outstanding resistance to corrosion, oxidation, and high temperatures. Aung Metals takes pride in its precise manufacturing processes, rigorous quality testing, and commitment to international standards, ensuring that their products are durable and strong. The Stainless Steel 347H Square Bars and Rods come in a variety of sizes and finishes, making them perfect for industries like chemical processing, power generation, petrochemicals, and construction, where reliability and performance are crucial.
These bars are made up of chromium (17–19%), nickel (9–13%), carbon (0.04–0.10%), along with manganese, silicon, and stabilizing niobium. The addition of niobium enhances resistance to intergranular corrosion and helps prevent carbide precipitation during welding and heat exposure. With a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of 40%, these bars demonstrate excellent creep strength, thermal stability, and mechanical durability, making them well-suited for high-temperature applications.
