摘　　要：研究了不同回火条件对30CrNiMo4.4V钢力学性能的影响.试验结果表明,30CrNiMo4.4V钢具有较宽的回火温度范围.经900℃淬火的30CrNiMo4.4V钢在500～600℃温度回火时,其强韧性可以达到良好的匹配.Effect of tempering process on the mechanical properties of 30CrNiMo4. 4V steel was investigated. The results show that 30CrNiMo4. 4V steel has a wider tempering temperature range. The 30CrNiMo4. 4V steel can obtain a favorable match between strength and toughness quenched at 900℃ then tempered at the temperature of 500 to 600℃.
