ASME SA213 TP304L(UNS S30403) Stainless Steel Seamless Tube Heat Exchanger Tube
AsSME SA213 TP304L Stainless Steel Seamless Tubes are a type of high-temperature and corrosion-resistant tubes made from austenitic stainless steel alloy， containing low carbon content to improve weldability and reduce the risk of intergranular corrosion. These tubes are widely used in lots of industrial applications such as chemical industry， petrochemicals， oil and gas plant， food processing equipment， pharmaceuticals， and so on. ASME AS213 TP304L SS seamless tubes have excellent resistance to corrosion， high strength， and durability.
