Structure and mechanical properties of ESR high strength steel 30NCD16(0.31C
1.41Cr
4.01Ni
0.52Mo) quenched at 840~930℃ and tempered at 350~625℃ have been tested. Results showed that optimum heat treatment process for high strength steel 30NCD16 was quenching at 840~870℃+ tempering at 560 ℃ to get fine and homogeneous sorbite structure
tensile strength of steel≥1200MPa and impact energy A
