Abstract
The present invention provides a heat treatment method for an alloy steel, which comprises the following steps: 1) heating the alloy steel to 800 DEG C at a rate of 150-350 DEG C/s and then holding the temperature for 25 s; 2) cooling the alloy steel from the step 1) to a temperature below a martensitic transformation temperature at a rate of 300 DEG C/s; and 3) reheating the alloy steel from the step 2) to 350 DEG C and holding the temperature for 20-25 min. Compared with a conventional method, the heat treatment method for an alloy steel disclosed by the present invention may allow an improvement in mechanical properties of the alloy steel while guaranteeing high strength of the alloy steel.
Description
Technical field
The present invention relates to steel technical field, particularly relate to the heat treatment method of a kind of steel alloy.
Background technology
Under normal circumstances, automobile high-strength steel are required for using, in hot procedure through hot pressing processing aftershaping
The structure property of steel changes (such as dynamically/static recovery and recrystallization etc.), different alloying elements and heating technique
Hot change behavior on its steel can produce impact, thus directly affects the performance of steel.
Summary of the invention
For solving the problems referred to above present in prior art and practical situation, the invention provides at the heat of a kind of steel alloy
Reason method, comprises the steps:
1) by steel alloy with 150 ~ 3500The speed of C/s is heated to 800 degrees Celsius, is then incubated 25s；
2) steel alloy step 1) obtained is with 3000The speed of C/s is cooled to below Martensite temperature；
3) steel alloy that step 3) obtains is reheated to 350 degrees Celsius, is incubated 20 ~ 25min.
Beneficial effect:
The heat treatment method of a kind of steel alloy disclosed by the invention, compares conventional method, high intensity same ensureing steel alloy
Time, it is also possible to improve its mechanical property.
Detailed description of the invention
Technical solution of the present invention is described in detail below.
The invention provides the heat treatment method of a kind of steel alloy, comprise the steps:
1) by steel alloy with 150 ~ 3500The speed of C/s is heated to 800 degrees Celsius, is then incubated 25s；
2) steel alloy step 1) obtained is with 3000The speed of C/s is cooled to below Martensite temperature；
3) steel alloy that step 3) obtains is reheated to 350 degrees Celsius, is incubated 20 ~ 25min.
Beneficial effect:
The heat treatment method of a kind of steel alloy disclosed by the invention, compares conventional method, high intensity same ensureing steel alloy
Time, it is also possible to improve its mechanical property.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
