Small punch creep test data for 2.25 Cr 1Mo V mod material at 560 °C and a load of 340 N (seventeenth repeat test)

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.本数据集依托一项旨在评估小冲杆（Small Punch, SP）试验方法可靠性的项目构建而成，该方法作为替代型力学测试技术，可用于老化设施组件的剩余寿命评估与完整性评定。 本次测试以经改性的2¼Cr-1Mo-V低合金铁素体钢为对象，该材料广泛用于制造石化厂的高温组件。该试验技术已被证实可便捷测定材料的蠕变与拉伸性能。不过，相较于常规单轴蠕变试验方法，本次研究重点关注了SP蠕变试验技术在评估材料因氢腐蚀与热老化导致的性能劣化方面的应用潜力。
