摘要

热轧状态下的铁素体不锈钢Y0Cr17SiS综合性能较差

不能满足加工使用要求

需进行退火处理

研究了退火温度750 ℃、800℃、850℃、900℃对Y0Cr17SiS钢Φ11 mm热轧材的组织和性能的影响。结果表明

经900℃2 h空冷退火

Y0Cr17SiS钢组织均匀、无析出物产生

抗拉强度为510 MPa

断后延伸率为36%

断面收缩率为65%

HBW硬度值为171。在不锈钢Y0Cr17SiS 35℃的5% NaCl水溶液的雾腐蚀测试能保持24 h不生锈。

Abstract

The comprehensive properties of ferrite stainless steel Y0Cr17SiS are poor in hot rolling state

which can not meet the requirements of processing and application

so it is needed to annealing treatment. The effects of annealing temperature of 750 ℃

800 ℃

850 ℃ and 900 ℃ on the microstructure and properties of Oil mm hot-rolled products of steel Y0Cr17SiS are studied. Results show that with 900 °C 2 h

air cooling annealing

the steel Y0Cr17SiS has uniform structure with out precipitates

its tensile strength is 510 MPa

elongation after fracture is 36%

reduction of area is 65%

and HBW hardness value is 171. It could maintain no rust for 24 h by salt corrosion fog test with 5% NaCl aqueous solution at 35 °C.
