Stainless Steel SUS310 Suppliers Singapore - SUS310, SUS310S, UNS S31008, 1.4840, 104845 

SUS310, combining excellent high temperature properties with good ductility and weldability, is designed for high temperature service. It resists oxidation in continuous service at temperatures up to 1150°C provided reducing sulphur gases are not present. It is also used for intermittent service at temperatures up to 1040°C.
 

SUS310S (UNS S31008) is used when the application environment involves moist corrodents in a temperature range lower than that which is normally considered “high temperature” service. The lower carbon content of 310S does reduce its high temperature strength compared to SUS310.

Like other austenitic grades these have excellent toughness, even down to cryogenic temperatures, although other grades are normally used in this environment.

Alternative grades to SUS310 stainless steels are given  

Grade Why it might be chosen instead of SS310
3CR12 Heat resistance is needed, but only to about 600°C.
SS304H Heat resistance is needed, but only to about 800°C.
SS321 Heat resistance is needed, but only to about 900°C. Subsequent aqueous corrosion resistance also required.
253MA (2111HTR) A slightly higher temperature resistance is needed than can be provided by 310. Better resistance to reducing sulphide atmosphere needed. Higher immunity from sigma phase embrittlement is required.

 

Corrosion Resistance of Stainless Steel 310 (SUS310s) 

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 SS316. 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 SS304 or SS316.
 

Heat Resistance of 310 Stainless Steel (SUS310 , SS310) 

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.

SUS310 is generally used at temperatures starting from about 800 or 900°C – above the temperatures at which SS304H and SS321 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.
