摘　　要：采用正交试验法研究了淬火加热温度、淬火保温时间、回火加热温度和回火保温时间对26CrMoNbTiB钻杆用钢强韧性的影响。结果表明,回火加热温度对实验钢的强度和伸长率影响最大,淬火加热温度次之。当淬火温度为910℃、保温时间为35 min,回火温度和时间分别为590℃和65 min时,26CrMoNbTiB钢的屈服强度为898 MPa,抗拉强度为973 MPa,伸长率为17.4%,具有良好的综合力学性能。In order to obtain good mechanical properties, the influences of quenching temperature, holding time, tempering temperature and holding time on strength and toughness of tested steel 26CrMoNbTiB drill pipe were studied. The results show that the influence of tempering temperature on the mechanical strength and elongation is greatest, followed by quenching temperature. When the quenching temperature is 910 ℃, holding for 35 rain, tempering temperature and time are 590 ℃ and 65 min, 26CrMoNbTiB steel, yield strength of 898 MPa, tensile strength of 973 MPa, elongation of 17.4%, the tested steel has good comprehensive mechanical properties.
