摘要
将蒸汽氧化处理及空气氧化处理后的T-250钢进行拉伸、电化学极化曲线、湿热、盐雾等试验测试,探究蒸汽氧化对T-250钢抗拉强度及伸长率等力学性能及不同环境下耐蚀性能的影响。结果表明,经蒸汽氧化处理的T-250钢具有良好的力学性能,强度能够达到1700 MPa以上,且相较于空气氧化处理具有更优良的隔绝腐蚀效果,未出现蒸汽引起的氢致延迟断裂现象。
T⁃250 steel after steam oxidation treatment and air oxidation treatment was tested by tensile,electrochemical polarization curve,damp heat,salt spray and other tests to explore the effect of steam oxidation on mechanical properties,such as tensile strength and elongation of the T⁃250 steel and its corrosion resistance in different environments.The results show that the T⁃250 steel treated by steam oxidation has good mechanical properties and better corrosion isolation effect than that treated by air oxidation,without obvious hydrogen induced delayed fracture caused by steam.
