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 Grades 304 or 316.
Heat Resistance
Good resistance to oxidation in intermittent service in air at temperatures up to 1040°C and 1150°C in continuous service. Good resistance to thermal fatigue and cyclic heating. Widely used where sulphur dioxide gas is encountered at elevated temperatures. Continuous use in 425-860°C range not recommended due to carbide precipitation, if subsequent aqueous corrosion resistance is needed, but often performs well in temperatures fluctuating above and below this range.
Grade 310 is generally used at temperatures starting from about 800 or 900°C - above the temperatures at which 304H and 321 are effective.
Heat Treatment
Solution Treatment (Annealing) - heat to 1040-1150°C and cool rapidly for maximum corrosion resistance. This treatment is also recommended to restore ductility after each 1000 hours of service above 650°C, due to long term precipitation of brittle sigma phase.
These grades cannot be hardened by thermal treatment.
Welding
Good characteristics suited to all standard methods. Grade 310S electrodes generally recommended for fusion welding. AS 1554.6 pre-qualifies welding of 310 with Grade 310 rods or electrodes.
"Dual Certification"
310 and 310S are sometimes stocked in "Dual Certified" form - mainly in plate and pipe. These items have chemical and mechanical properties complying with both 310 and 310S specifications.

Applications
Typical applications include:
        Furnace parts
         Oil burner parts
       Carburising boxes         
       Heat Treatment baskets and jigs
      Heat Exchangers
      Welding filler wire and electrodes
