Chemical Composition
Stainless Steel 347 Tubes are stabilized austenitic stainless steel tubes containing niobium (columbium), designed to resist intergranular corrosion after welding or prolonged exposure to high temperatures. ASTM A213 TP347 Seamless Tube is widely used in heat exchangers, pressure vessels, refineries, power plants, chemical processing, fertilizer plants, and petrochemical industries because of its excellent oxidation resistance, high-temperature strength, and corrosion resistance. These tubes are available in seamless, welded, heat exchanger, capillary, and Schedule 40 configurations.
Detailed Information
Stainless Steel 347 Tubes Manufacturer, Supplier & Exporter
We are a trusted 347 SS Tube Manufacturer in India, supplying premium quality Stainless Steel 347 Tubes to customers across domestic and international markets. Our product range includes SS 347 Seamless Tube, welded tubes, instrumentation tubing, 347 Stainless Steel Tubing, capillary tubes, hydraulic tubes, condenser tubes, and SS TP347 Heat Exchanger Tube manufactured according to international quality standards.
Manufactured using high-grade UNS S34700 Tubing, these tubes contain niobium stabilization, which significantly improves resistance to chromium carbide precipitation during welding. This makes them an excellent choice for elevated temperature applications where standard 304 or 304L stainless steel may become susceptible to intergranular corrosion.
As an experienced SS 347 Tube Supplier, we provide products that comply with ASTM, ASME, DIN, EN, ISO, and GOST standards. Every tube undergoes rigorous testing to ensure dimensional accuracy, corrosion resistance, mechanical strength, and long service life.
