TP309S is an austenitic chromium-nickel stainless steel with a low
carbon content that provide excellent corrosion resistance and heat
resistance plus good strength at room and elevated temperatures.
Corrosion Resistance
TP309S provides excellent general corrosion resistance. It is more
resistant to marine atmospheres than TP304. It exhibits high resistance
to sulfite liquors and is useful for handling nitric acid,
nitric-sulfuric acid mixtures, and acetic, citric, and lactic acids.
It exhibits good scaling resistance in both continuous and intermittent service, but the alloy should not be used above 1800°F (982°C) for intermittent service.
UNS S30908
Application
Heat exchanger tubing, condenser tubing, pipelines, cooling and heating coils in the refinery, chemical processing, petrochemical industries
