Located in Cape Town, South Africa, Phehlukwayo Metals is a leading supplier specializing in Stainless Steel 347 Round Bars/Rods intended to meet the needs of demanding industrial applications. These bars are made with premium grade of stainless steel that ensures that it exhibits a fabulous resistance to intergranular corrosion even when placed in the condition of high-temperature zones. Stainless Steel 347 Round Bars and Rods have a versatile use through various industries including Aerospace, Chemical processing, and Power generation. Where high durability, and thermal stability is highly required. Its superior weldability and machinability can be used for fabricating products like flanges, fasteners, and fittings. We supply top-notch quality products that stand up to the governing boards of various global standards.
SS 347 Round Bars and Rods are made from an austenitic stainless steel alloy stabilized with niobium, offering exceptional resistance to intergranular corrosion and oxidation in high-temperature environments. The alloy typically comprises 17-19% chromium, 9-13% nickel, 0.08% carbon, 2% manganese, 1% silicon, and trace amounts of niobium (10x the carbon content). These bars provide excellent mechanical strength, superior thermal conductivity and enhanced weldability. They are non-magnetic in nature resistant to scaling and perform reliably under temperatures up to 870°C. With outstanding toughness and durability they are ideal for demanding applications in industries like Aerospace, Chemical and Power generation.
