摘　　要：采用水基单介质或马氏体等温分级淬火油淬火可使钢件获得优良的性能,并明显减小淬火畸变和开裂倾向。聚合物水溶性淬火剂应按照钢件的淬透性、工件质量、形状和工件的技术性能要求等作合理的选择。马氏体等温分级淬火油适用于中等和高淬透性合金钢件的淬火冷却,可用于开式槽、闭式槽或密封箱式炉中的淬火槽等场合。Quenching in single aqueous solution or martempering oil may permit steel part to obtain satisfactory property and to significantly reduce its distortion amount and sensitivity to cracking.The water-soluble polymer quenchants should be reasonably selected in accordance with the hardenability,mass,configuration and property requirements of the steel part to be hardened.The martempering oil is suitable for quenching medium-hardening and deep-hardening alloy steels,and suitable for open or closed quenching system or sealed box type furnace.
