310H has good oxidation resistance. It can be used intermittently in the air with temperature up to 1040 ° C and continuously in the environment with temperature up to 1150 ° C. It has good thermal fatigue resistance and cyclic heating performance. It is widely used in high temperature sulfur dioxide gas environment. Due to carbide precipitation, if there are subsequent requirements for the corrosion resistance of the material to aqueous solution, it is not recommended to use continuously in the temperature range of 425-860 ° C, but it usually performs well above and below this temperature range. It is easy to occur in the temperature range of 650-900 ℃ σ Phase embrittlement.
