Stainless Steel 347 Rectangular Bars are sourced from a trusted manufacturer and supplier in Safat, Kuwait, known for delivering top-notch bars that excel in high-temperature and corrosive industrial settings. With niobium added for stabilization, SS 347 boasts exceptional resistance to intergranular corrosion, particularly after welding or extended heat exposure. These rectangular bars are crafted with precise dimensions, a smooth surface finish, and impressive mechanical strength, ensuring reliable performance in tough applications. Industries across Kuwait rely on Stainless Steel 347 Rectangular Bars for their durability, thermal stability, and weldability, making them perfect for chemical processing equipment, heat exchangers, power plant components, and structural fabrication.
Stainless Steel 347 Rectangular Bars are made up of 17–19% chromium, 9–13% nickel, and are stabilized with niobium (columbium), which helps prevent carbide precipitation during welding and high-temperature use. This alloy provides outstanding corrosion resistance, can withstand oxidation up to 900°C, and maintains strong mechanical stability. SS 347 features high tensile and yield strength, good creep resistance, and dependable toughness even when subjected to thermal cycling. Its mechanical and chemical stability make it a great choice for applications that involve heat exposure, pressure, and corrosive environments, all while ensuring good formability and weldability.
