Grade 310H stainless steel is chiefly used in the heat treatment industry, and the chemical process industry.
Containers for hot concentrated acids, ammonia, and sulfur dioxide
Used along with hot acetic and citric acid in the food processing industry.

The high chromium content – intended to increase high temperature properties – also gives this grades good aqueous corrosion resistance.
In high temperature service, 310H exhibits good resistance to oxidising and carburising atmospheres.
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 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
