查询词典 tensile strength

The results show that proper RRA heat treatment can improve SCC properties with retention of the high strength of T6 level. After pre-aging at 100℃ for 24 h, retrogression at 200℃ for 7 min, and reaging at 100℃ for 24 h, the ultimate tensile strength, yield strength and elongation of the alloy are 795 MPa, 767 MPa and 9.1%, respectively. Meanwhile the failure time of the alloy applied to tensile strength of 210 MPa in 3.0%NaCl+0.5% H2O2 corrosion condition is longer than 720 h.
