摘要/Abstract

摘要： 以ASME SA517 Gr. F为对标材料，设计高压储氢压力容器用可焊接高强度钢板Q690DR。通过优化化学成分、热处理工艺精准调控，可获得屈服强度不低于690 MPa，抗拉强度800～900 MPa，冲击性能良好的高强度可焊Q690DR钢板。经系列抗氢性能评价试验，Q690DR具有良好的抗氢脆性能，较低的氢脆敏感性。对比10 MPa氢气与同压力氮气环境下的慢拉伸试验结果，Q690DR的相对延伸率约为96.4%，相对断面积收缩率约为97.0%，具有较低的氢脆敏感性。10 MPa氢气环境下Q690DR测得的断裂韧性KIH约为305 MPa·m^0.5。整体看，工业试制的Q690DR钢板各项指标性能优良稳定，符合相关标准及用户技术条件，可以用作实际工程项目高压储氢容器的建造。

Abstract: The article designs high-strength, weldable steel plate Q690DR for high-pressure hydrogen storage vessels, using ASME SA517 Gr. F as the benchmark material. By optimizing the chemical composition and heat treatment process, a steel plate with a yield strength of not less than 690 MPa, tensile strength of 800-900 MPa, and good impact performance can be obtained. The Q690DR has been evaluated through a series of hydrogen resistance tests, demonstrating good hydrogen embrittlement resistance and low hydrogen sensitivity. Compared with the slow tensile test results in a 10 MPa nitrogen environment, the relative elongation of Q690DR is about 96.4%, and the relative reduction of area is about 97.0%, indicating low hydrogen embrittlement sensitivity. The fracture toughness KIH of Q690DR measured in a 10 MPa hydrogen environment is about 305 MPa·m^0.5. Overall, the industrially tested Q690DR steel plate has excellent and stable performance indicators, complying with relevant standards and user technical conditions, and can be used for the construction of high-pressure hydrogen storage vessels in practical engineering projects.
