Situated in Dubai, UAE, Al Summan Metals is a top supplier that focuses on Stainless Steel 347 Round Bars/Rods designed to satisfy the requirements of challenging industrial applications. These bars are crafted from a premium grade of stainless steel that guarantees it displays remarkable resistance to intergranular corrosion even when subjected to high-temperature zone conditions. Stainless Steel 347 Round Bars and Rods serve a flexible purpose across numerous industries such as Aerospace, Chemical processing, and Power generation. Where great durability, and thermal stability is greatly needed. Its excellent weldability and machinability makes it suitable for manufacturing products like flanges, fasteners, and fittings. We deliver top-quality products that meet the governing boards of various global standards.
SS 347 Round Bars and Rodsare manufactured from an austenitic stainless steel alloy stabilized with niobium, delivering outstanding resistance to intergranular corrosion and oxidation in high-temperature settings. The alloy generally consists of 17-19% chromium, 9-13% nickel, 0.08% carbon, 2% manganese, 1% silicon, and small quantities of niobium (10x the carbon content). These bars offer excellent mechanical strength, superior thermal conductivity and improved weldability. They are non-magnetic by nature, resistant to scaling and perform dependably under temperatures up to 870°C. With remarkable toughness and durability they are well suited for demanding applications in industries such as Aerospace, Chemical and Power generation.
