TP310 is a highly alloyed austenitic stainless steel used for
high-temperature applications. The high chromium and nickel contents
give the steel excellent oxidation resistance as well as high strength
at high temperatures.
Corrosion Resistance
The high chromium content - intended to increase high temperature
properties - also gives these grades good aqueous corrosion resistance.
The PRE is approximately 25, and seawater resistance about 22°C, similar
to that of Grade 316. Excellent resistance at normal temperatures, and
when in high temperature service exhibits good resistance to oxidising
and carburising atmospheres.
Resists fuming nitric acid at room
temperature and fused nitrates up to 425°C.
Subject to stress corrosion cracking but more resistant than TP304 or TP316.
Application
Heat exchanger tubing, condenser tubing, pipelines, cooling and heating coils in the refinery, chemical processing, petrochemical industries, steam boilers
