Small punch creep test data for 2.25 Cr 1Mo V mod material at 560 °C and a load of 340 N (eighth 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.本数据集源自一项旨在评估小冲杆（Small Punch, SP）试验法可靠性的科研项目，该技术作为替代力学测试手段，可用于评估老化装置中部件的剩余寿命与完整性。 试验以改良型2¼Cr-1Mo-V低合金铁素体钢为试样材料，该材料被广泛用于制造石化厂的高温部件。 研究表明，该试验技术可便捷测定材料的蠕变与拉伸性能。 然而，相较于传统单轴蠕变试验方法，本研究特别关注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。
