調質工藝對590 MPa級鋼板力學性能的影響

Quenching-tempering Process Effect on Microstructure and Properties of 590 MPa High Strength Thick Plate

  • 摘要: 針對590 MPa級工程機械用高強度厚鋼板的調質工藝進行實驗室條件下的系統研究,得到適應不同成分的鋼板的淬火一回火工藝制度,即淬火溫度910~920℃,回火溫度為550~580℃.在該工藝制度下,該鋼種可獲得符合使用要求的綜合力學性能指標.

     

    Abstract: A new quenching-tempering technology system is gotten, in which the quenching temperature is about 910~920℃ and the tempering temperature is about 550~580℃. With using this technology, the mechanical properties of the 590 MPa high strength thick plate are better satisfaction for the using demand. The new technology system is available for the steel plate of different composition.
