The invention belongs to the technical field of design and manufacturing of technological equipment for aero-engines, and relates to a high-temperature lasting creep performance testing device and method. The device comprises a testing cabin, a sample clamping and stretching mechanism and a corrosion medium supply mechanism, a flame generator is arranged at one end of the testing cabin, the sample clamping and stretching mechanism is arranged on the testing cabin and partially extends into the testing cabin, and the corrosion medium supply mechanism is connected with the flame generator. A to-be-tested high-temperature-resistant material sample is clamped and fixed in the test cabin through the sample clamping and stretching mechanism and is connected with the electronic tensile machine through the sample clamping and stretching mechanism, and a stretching load is provided for the to-be-tested high-temperature-resistant material sample; the high-temperature-resistant material sample is placed in the testing c
