Bereket Pipes, a reputable manufacturer and supplier located in Addis Ababa, Ethiopia, specializes in high-quality Stainless Steel 347 and 347H Seamless Pipes, perfect for high-temperature and corrosive settings. These pipes are crafted with precision, utilizing cutting-edge technology and top-notch raw materials to guarantee outstanding durability and reliability. Renowned for their resistance to intergranular corrosion and impressive mechanical strength, Bereket Pipes’ Stainless Steel 347 and 347H Seamless Pipes are a go-to choice for industries like petrochemical, power generation, refineries, and food processing, where heat resistance and structural integrity are vital for long-lasting performance.
The Stainless Steel 347 and 347H Seamless Pipes are stabilized with niobium and include elements such as chromium (17–19%), nickel (9–13%), carbon, manganese, silicon, and phosphorus. The addition of niobium boosts their resistance to carbide precipitation and corrosion. These grades showcase a tensile strength of about 515 MPa, yield strength of 205 MPa, and an elongation of 40%. With a higher carbon content, Stainless Steel 347H provides enhanced creep strength and heat resistance, making both alloys ideal for high-temperature applications, along with excellent weldability and toughness.
