Abstract

Abstract: Effects of quenching temperature, cooling method and tempering temperature on microstructure and mechanical properties of the 36CrNi3MoV steel forging for hot isostatic pressing machine were studied. The results show that when quenched between 770-860 ℃ and tempered at 600 ℃, the obtained microstructure is tempered martensite. With the increase of quenching temperature, the strength increases, while the impact property and plasticity decrease. When quenched with different cooling methods, the water quenched microstructure is the most uniform. The strength of water quenched steel is slightly higher than that of oil quenched. When tempered in the range of 580-620 ℃, with the increase of tempering temperature, the strength decreases, but the impact property and plasticity increase. The optimal heat treatment process consists of austenitizing in the range of 830-860 ℃, water quenching and then tempering at 600 ℃,which can achieve mechanical properties that meet the design requirements and NB/T 47008-2017.
