Abstract

Abstract: The effect of tempering at 100~700 ℃ on structure and mechanical properties of a new precipitation hardening stainless steel 1Cr16Ni3Cu1MoW has been studied. The test results showed that with solid solution treated at 1070 ℃ for 1 h,oil cooling,cold treated at -70 ℃ for 2 h,then aged at 485 ℃ for 2 h,the tensile strength on of stainless steel 1Cr16Ni3Cu1MoW was 1475 MPa and the impact energy Axtp was 119 J; and with solid solution treated at 1070 ℃ for 1 h,oil cooling,cold treated at - 192 ℃ for 2 h then aged at 500 ℃ for 2 h,the peak tensile strength og of steel was 1605 MPa and the impact energy A_ku2 was 88 J.
