STS 347 및 STS 310S 오스테나이트계 스테인리스강의 고온 가스질화 열처리 특성 연구
The influence of high temperature gas nitriding (HTGN) in STS347 and STS310S steels was experimentally investigated. The HTGN was carried out at 1,050℃~1,150℃ for 10 hrs in a gaseous atmosphere containing 1 kg/mm2 of nitrogen. After HTGN, fine precipitates of Cr2N and NbN appeared in austenite on th...

| Abstract | The influence of high temperature gas nitriding (HTGN) in STS347 and STS310S steels was experimentally investigated. The HTGN was carried out at 1,050℃~1,150℃ for 10 hrs in a gaseous atmosphere containing 1 kg/mm2 of nitrogen. After HTGN, fine precipitates of Cr2N and NbN appeared in austenite on the surface of STS 347, while nitrogen pearlite, which was layeredof Cr2N and austenite alternatively, appeared in austenite on the surface of STS 310S. The surface hardness of HTGN-treated, STS 347 and STS 310S specimens was 250~360 Hv and 270~400 Hv, respectively, depending on the temperature of HTGN. The nitrogen content was analyzed 1.4 wt% and 1.6 wt% at the surface layer of STS 347 and STS 310S steels, respectively. In addition, an improvement in the corrosion resistance of HTGN treated specimens was observed. |
