摘　　要：ASME标准钢板对于短时高温抗拉数据无规定,但设备设计人员在校核时又要用到此数据,于是有些设计文件在技术要求中将ASME II卷表U的数据作为材料验收的标准。针对此种做法引发的争议及涉及的主要问题进行试验验证和分析探讨。研究结果表明,ASME II卷D篇表U中的数据是基于室温抗拉强度保证值,并根据拟合曲线将室温保证值提高了10%得到的,实测数据与ASME规范数据不一致,部分材料在250~350℃存在动态应变时效现象,但仍不满足设计要求。材料经模拟焊后热处理后性能下降,难以到达交货态的要求。给出了短时高温抗拉强度的选用建议。The ASME steel plate has no provisions for short-term high temperature tensile data however the equipment designer needs to use this data when checking and the ASME Ⅱ volume,table U data should be used as the material acceptance standard in the technical requirements of design documents.The dispute caused by this method and the main problems involved were tested,analyzed and discussed.The results show that,the data in ASME Ⅱ volume D,table U is based on the guaranteed value of room temperature tensile strength,and the guaranteed value of room temperature is increased by 10% according to the fitting curve.The measured data are inconsistent with ASME code data.The dynamic strain aging phenomenon exists at 250~350℃,but still can not meet the design requirements.The performance of the material is reduced after simulated post-weld heat treatment,and it is difficult to reach the requirements of the delivery state.Suggestions for the selection of short-term high temperature tensile strength are given.
