ASTM A312 TP317/317L Seamless Tube with 100% ET,UT for Boiler / Heat Exchanger Application
The stainless steel 317L U Tube is a special type of tube manufactured particularly for heat exchangers. The tubes are made in U shape and are used in repeating rows in the heat exchanger applications. The material has nickel, chromium, carbon, manganese, phosphorus, silicon, sulfur and molybdenum in its composition. It has an excellent corrosion resistance compared to other stainless steels, alloy 317L is non-magnetic in the annealed condition. It cannot be hardened by heat treatment.
Stainless steel TP317L is a low carbon version of TP317 stainless steel. It has the same high strength and corrosion resistance as 317 steel but can produce stronger welds due to the low carbon content.
