ASTM A688 TP316N Stainless Steel Tube For High-Pressure Feedwater Heaters
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 TP316N grade is a nitrogen-strengthened version of the standard TP316. The addition of nitrogen significantly increases its mechanical strength without compromising its core corrosion resistance.
We offer ASTM A688 TP316N 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.
