中温回火

对于大尺寸零件，宜采用淬火+低温回火或中温回火处理。

For machine parts large in size , a low to medium temperature tempering after quenching is suitable .

对于要求高强度的零件，建议在Ac3-（5～15）℃淬火并中温回火。

If machine parts require a high strength as well as a high toughness , the quenching temperature is proposed to be Ac_3 - ( 5 ~ 15 )℃ and the tempering temperature to be medium .

试验表明弹簧片的淬火加热温度应定为840～850℃，经415℃±10℃中温回火后可获得回火屈氏体组织，达到较高的弹性极限、疲劳强度，得到满意的使用效果。

The test indicates that quenching temperature of the spring would be 840 ℃ - 850 ℃, and after 415 ± 10 ℃ tempering the tempering-Troostite structure would be obtained . The higher elastic limit , the higher fatigue limit would be reached , and satisfactory result would be obtained .
