Small punch creep test data for 2.25 Cr 1Mo V mod material at 600 °C and a load of 210 N

Data collection created in the scope of a programme designed to evaluate the reliability of the Small Punch (SP) testing method as an alternative mechanical test technique for evaluation of the residual life and integrity assessment of components in ageing plants. Tests were performed on the low alloy - 2¼Cr 1Mo V modified ferritic steel, widely selected for construction of high temperature components in petrochemical plants. The technique was shown to facilitate determination of both creep and tensile properties of materials. However, special attention was directed to the potential of the SP creep testing technique for assessing the deterioration of material due to hydrogen attack and thermal ageing, in comparison with conventional uniaxial creep methods.本数据集依托某评估项目采集而成，该项目旨在验证小冲杆（Small Punch, SP）试验方法的可靠性——该方法可作为替代力学测试技术，用于评估老化工业装置中组件的剩余寿命与完整性。 试验以经改性的2¼Cr-1Mo-V低合金铁素体钢为对象，此类材料广泛用于石化厂高温组件的制造。研究表明，该试验技术可同时测定材料的蠕变与拉伸性能。不过相较于传统单轴蠕变试验方法，本次研究重点关注了SP蠕变试验技术在评估材料因氢侵蚀与热老化引发的性能劣化方面的应用潜力。
