Material performance：

(1) The oxidation resistance and carburizing resistance are better than 310S, and the toughness and solderability are slightly [TJC STEEL]worse than 310S.

(2)  The highest service temperature is 1200℃, the highest continuous use temperature is 1150℃, and the highest intermittent use temperature is 1050~1100℃.

(3) Sensitive to sulfur-[TJC STEEL]containing atmosphere, there is a precipitate embrittlement tendency at 600~800℃.

(4) good resistance to general corrosion performance.
