Maduka Metals, a top-notch manufacturer and supplier located in Abuja, Nigeria, is well-known for its high-quality **Stainless Steel 347H Round Bars and Rods**. These bars are designed to perform exceptionally well in high-temperature and corrosive settings, making them perfect for tough industrial tasks. With a commitment to precision and international quality standards, Maduka Metals guarantees outstanding durability, strength, and reliability. The 347H grade, which is stabilized with niobium, provides enhanced resistance to intergranular corrosion and creep strength, making it a go-to choice for sectors like petrochemical, power generation, and chemical processing.
**Stainless Steel 347H Round Bars and Rods** mainly consist of **iron**, along with **17–19% chromium**, **9–13% nickel**, and a touch of **niobium (columbium)** to stabilize the structure. The carbon content, which is around **0.04–0.10%**, boosts high-temperature strength. This austenitic stainless steel showcases impressive **tensile strength of about 515–700 MPa**, remarkable **oxidation resistance**, and excellent **creep and stress-rupture properties** at high temperatures. The addition of niobium helps prevent carbide precipitation during welding and heat exposure, ensuring long-lasting structural stability and corrosion resistance.
