研究了淬火温度对低合金超高强度工程机械用钢组织及性能的影响。结果表明:实验钢经不同温度(850、900、950和1000℃)淬火后力学性能变化不大,但900℃淬火时综合力学性能最佳。
The effect of quenching temperature on microstructure and properties of low alloy high strength engineering machine steel was studied. The results show that the mechanical properties of the experimental steel after quenching at different temperatures (850, 900, 950 and 1000 ℃) have little change, but the mechanical properties at 900 ℃ are the best.
