Research on Mechanics Performance of TP304H Austenitic Stainless Steel in the Process of Aging at High Temperature

Abstract:

The aging of initial TP304H austenitic stainless steel was simulated at 650°C,700°C and 750°C for 30d,60d and 150d respectively. These samples and the others, the samples aging for 15kh, 78kh and 80kh at the same temperature during the actual operation, were studied through the hardness test and tensile test to analyze the mechanics performance and its changing of TP304H steel. The results showed that for the same aging time, the hardness, yield strength and tensile strength of TP304H steel rise firstly and then turn to decrease with the growth of the aging temperature, while at the same aging temperature, the hardness, yield strength and tensile strength increase with the extension of aging time, which is similar with the increase tendency of mechanics parameters of TP304H aging during actual operation.
