Anucha Metals, a well-respected manufacturer and supplier located in Bangkok, Thailand, specializes in providing top-notch Stainless Steel 347H Round Bars and Rods tailored to meet a variety of industrial needs. Renowned for their precision, durability, and adherence to international standards, Anucha Metals offers products that are trusted for their performance in challenging environments. Stainless Steel 347H is a high-carbon stabilized grade specifically designed to resist intergranular corrosion at high temperatures. With impressive creep strength and oxidation resistance, these Round Bars and Rods are widely utilized in industries like petrochemical, power generation, construction, and chemical processing, ensuring long-lasting service.
The composition of Stainless Steel 347H Round Bars and Rods primarily includes iron, along with 17–19% chromium, 9–13% nickel, and 0.04–0.10% carbon to enhance high-temperature strength. The addition of small amounts of niobium and tantalum helps stabilize the material against carbide precipitation. These bars boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. They maintain excellent hardness, creep resistance, and mechanical stability, even under high operating temperatures. The higher carbon content gives Stainless Steel 347H superior mechanical properties compared to standard 347, making it ideal for high-stress applications.
