ASME SA249 TP304 304L SUS304 1.4301 Welded Tube For Boiler Condenser
SS 304 Welded Tubes are non-magnetic, chromium-nickel austenitic steel products. Our 304 Stainless Steel Welded Tubes are built to withstand even harsh usage.
The ASME SA249 TP304/304L Tube is designed with a superior composition consisting of nickel and chromium with other alloying elements. The content embedded within these tubes gives them excellent resistance to reductive and corrosive media.
Austenitic stainless steel pipes produced using specified SA 249 TP304 Material are designed to be used in applications involving tubing for either boiler, superheater, heat exchanger, or condenser. Furnishing of this ASTM specified A 249 Tp 304 Stainless Steel Welded Tube is to be performed in the heat treated condition while keeping in accordance with the required solution temperature as well as the quenching method.
