Stainless Steel 347 / 347H Bars & Rods are manufactured from niobium-stabilized austenitic stainless steel containing chromium and nickel, offering a useful combination of corrosion resistance, mechanical strength, and stability during prolonged exposure to elevated temperatures. Chromium helps provide resistance to general corrosion and oxidation, while nickel contributes to toughness, ductility, and structural stability. The addition of niobium stabilizes the alloy by combining with carbon and helps limit chromium carbide precipitation during high-temperature exposure, which supports resistance to intergranular corrosion. Stainless Steel 347H contains a higher controlled carbon level than standard 347, providing improved high-temperature strength and creep resistance for demanding service conditions. Available in various diameters, lengths, profiles, and surface finishes, these bars and rods are suitable for machining and fabrication into different industrial components. Their combination of heat resistance, corrosion resistance, mechanical stability, and durability makes Stainless Steel 347 / 347H Bars & Rods suitable for chemical-processing equipment, petrochemical plants, heat exchangers, furnace components, power-generation systems, aerospace applications, high-temperature piping, exhaust systems, and other industrial equipment exposed to elevated temperatures.

Stainless Steel 347 / 347H Bars & Rods are manufactured from niobium-stabilized austenitic stainless steel containing chromium and nickel, providing a strong combination of corrosion resistance, toughness, mechanical strength, and performance under elevated-temperature conditions. Chromium helps the alloy resist general corrosion and oxidation, while nickel supports ductility and structural stability during demanding service. Niobium is added as a stabilizing element and combines preferentially with carbon, helping minimize chromium carbide precipitation when the material is exposed to high temperatures for extended periods. This stabilization helps maintain resistance to intergranular corrosion, particularly after welding or prolonged heating. Stainless Steel 347H contains a higher controlled carbon content than standard 347, which provides enhanced strength and creep resistance for high-temperature service. Available in various diameters, lengths, profiles, and surface finishes, these bars and rods can be supplied for machining, fabrication, and engineered component manufacturing. With their combination of thermal stability, corrosion resistance, strength, and durability, Stainless Steel 347 / 347H Bars & Rods are suitable for chemical-processing equipment, petrochemical systems, heat exchangers, furnace components, power-generation equipment, aerospace applications, high-temperature piping, exhaust systems, and other industrial components exposed to prolonged heat and demanding operating conditions.
