Specifications
ASTM A688 specification covers seamless and welded austenitic stainless steel feedwater heater tubes including those bent,if specified, into the form of U-tubes for application in tubularfeed-water heaters. The TP304L grade is a low-carbon variation of the classic 18/8 stainless steel (304), providing excellent corrosion resistance, particularly against sensitization (carbide precipitation) during welding.
We offer ASTM A688 TP304L seamless and welded stainless steel tube for feedwater heaters, Austenitic stainless steel and Ferritic stainless steels, surface condition in annealing and pickling, or bright annealed finishing, used in heat exchanger, boiler, condenser, heat transfer system.
