310/310S Stainless steel are austenitic stainless steel grades with high nickel and high chromium contents, 310 and 310S grades contain 25% chromium and 20% nickel, making them superior corrosion resistance, resistance to oxidation and heat resistance.
310S stainless steel is austenitic chromium-nickel stainless steel (0.08% max carbon) with good oxidation resistance and strength at high temperatures. It resists oxidation in continuous service up to 2000ºF gave decreasing sulphur gasses are not present. It is additionally utilized for intermittent service at temperatures up to 1900°F because it resists rescaling and has a low coefficient of expansion. This factor reduces the tendency of the steel to warp in heat service.

Corrosion Resistance Of 310/310S Stainless Steel
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 is about 22°C, similar to that of Grade 316. In high-temperature service, they exhibit good resistance to oxidising and carburising atmospheres. Resist fuming nitric acid at room temperature and fused nitrates up to 425°C.
The high carbon contents of all except 310L do make these grades susceptible to sensitisation and hence intergranular corrosion after elevated temperature exposure or welding. 310 is subject to stress corrosion cracking but more resistant than Grades 304 or 316.
Heat Resistance Of 310/310S Stainless Steel
Grades 310/310S have good resistance to oxidation in intermittent service in air up to 1035°Cand 1050°Cin continuous service. The grades are resistant to oxidation, sulfidation and carburisation.
Heat Treatment Of 310/310S Stainless Steel
Solution Treatment (Annealing)
Heat to 1040-1150°C and cool rapidly for maximum corrosion resistance. This treatment is also recommended to restore ductility after every 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 Of 310/310S Stainless Steel
Good characteristics suited to all standard methods. Grade 310S electrodes are generally recommended for fusion welding. AS 1554.6 pre-qualifies welding of 310 with Grade 310 rods or electrodes.
Typical Applications Of 310/310S Stainless Steel
310/310S Stainless Steel is capable of applications in reducing sulphur atmospheres containing H2S. They are widely used in moderately carburising atmospheres, as encountered in petrochemical environments. For more severe carburising atmospheres other heat-resisting alloys should be selected. Grade 310 is not recommended for frequent liquid quenching as it suffers from thermal shock. The grade is often used in cryogenic applications, due to its toughness and low magnetic permeability.

Dual Certification
310H and 310S are often produced in “Dual Certified” form – mainly in plate and pipe. These items have chemical and mechanical properties complying with both 310H and 310S specifications. Products complying with 310 only or dual-certified 310 and 310S may have a carbon content below 0.04% which will not be acceptable for some high temperature applications.

310H has 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 is not recommended due to carbide precipitation if subsequent aqueous corrosion resistance is needed, but it often performs well in temperatures fluctuating above and below this range. Prone to sigma phase embrittlement in the temperature range 650 – 900°C.
Grade 310H is generally used at temperatures starting from about 800 or 900°C above the temperatures at which 304H and 321 are effective.
