摘要
试验了电渣重熔高强度钢30NCD16(％:0．31C、1．41Cr、4.01Ni、0．52Mo)840-930℃淬火、350-625℃回火时的组织和力学性能。结果表明,高强度钢30NCD16最佳热处理工艺为840-870 oC淬火+560℃回火,可获得细致均匀的索氏体组织,钢的抗拉强度≥1 200 MPa,冲击功AKU5≥50 J。
Structure and mechanical properties of ESR high strength steel 30NCD16 （ 0. 31C, 1.41 Cr, 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 ≥1 200 MPa and impact energy AKU5 ≥50 J.
