Grade 1, Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10, Grade 11;
Low temperature carbon steel pipe quenching temperature in A3 + (30 ~ 50) ℃, in practice, is usually set to the upper limit. High quenching temperature heat pipe can make low speed, surface oxidation reduction, and can improve work efficiency. The workpiece is uniform austenite, will require sufficient holding time. If the actual installed furnace capacity, would need to be appropriate to extend the holding time. Otherwise, there may be insufficient hardness due to uneven heating caused by the phenomenon. However, the holding time is too long, will also appear coarse grains, oxidation and decarbonization serious ills affecting quenching quality. We believe that if installed furnace is greater than the process documents, heating holding time to be extended 1/5.

Low temperature carbon steel pipe because of low hardenability, it should adopt a large cooling rate of 10% salt solution. Workpiece into the water, should hardenability, but not chilled, if 45 # precision steel chilled in brine, it is possible cracking of the workpiece, this is because when the workpiece is cooled to about 180 ℃, the austenite rapidly converted to horse s body tissue caused by excessive stress due. Therefore, when the quenching and tempering steel quickly cooled to this temperature range, the approach should be taken to slow cooling.

As the water temperature is difficult to grasp, accountable experience in operation, when the water stops dithering artifacts, you can water cooled (eg oil cooler can be better). In addition, the workpiece into the water, appropriate action should still be in accordance with the geometry of the workpiece, as regular exercise. Stationary cooling medium plus stationary workpiece, resulting in uneven hardness, stress uneven leaving large deformation of the workpiece, and even cracking.
