314,1.4841, 1Cr25Ni20Si2 Austenitic High Silicon Heat Resisting Stainless Steel- TJC STAINLESS.

314 is an austenitic stainless steel. Due to its high silicon content and high [TJC STAINLESS]oxidation resistance, 314 is mainly used as a heat resistant steel.

Material performance：
(1) The oxidation resistance and carburizing resistance are better than 310S, and the toughness and solderability are slightly [TJC STAINLESS]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 STAINLESS]containing atmosphere, there is a precipitate embrittlement tendency at 600~800℃.
(4) good resistance to general corrosion performance.
