Abstract

The invention discloses a kind of 0Cr13Ni8Mo2Al precipitation-hardening stainless steels cold treatment method, its step is：First by 0Cr13Ni8Mo2Al steel at 1040 DEG C forging and molding, deflection is 50%, final forging temperature >=850 DEG C；After forging, 0Cr13Ni8Mo2Al steel forgings are inserted in heating furnace, furnace cooling；0Cr13Ni8Mo2Al steel forgings are heated to 927 DEG C of insulation 360min, the straight room temperature of water-cooled again；Taking-up is inserted in icehouse, transfer time≤120 second, and icehouse temperature is subzero 50 DEG C, keeps 180min；540 DEG C of insulation 240min, air cooling are reheated to again.The method can make 0Cr13Ni8Mo2Al steel forgings be fully converted to martensitic structure, improve forging performance.The method is for the treatment of 0Cr13Ni8Mo2Al precipitation-hardening stainless steels.

Description

0Cr13Ni8Mo2Al precipitation-hardening stainless steel cold treatment methods
Technical field
The present invention relates to a kind of cold treatment method, the more particularly to cold place of 0Cr13Ni8Mo2Al precipitation-hardening stainless steels Reason method.
Background technology
0Cr13Ni8Mo2Al steel is a kind of martensitic precipitation of function admirable.Precipitation-hardening stainless steel Heat treatment is the important process means for obtaining good combination property, and its Technology for Heating Processing is complicated, only by the temperature of defined, Time, cooling velocity are controlled can just obtain preferable performance.General martensitic precipitation is in suitable solid solution Temperature carries out air cooling and can be completely transformed into martensite, and 0Cr13Ni8Mo2Al steel can not completely change martensite as a class Steel grade, it is sometimes desirable to increase adjustment operation, forging performance can be ensured.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind and uses cold treatment method, to 0Cr13Ni8Mo2Al steel forgings Intermediate treatment is carried out, forging is fully converted to martensitic structure, improve the performance of 0Cr13Ni8Mo2Al steel forgings.
In order to solve the above technical problems, 0Cr13Ni8Mo2Al precipitation-hardening stainless steels cold treatment method of the present invention, its Technical scheme is comprised the following steps：
By 0Cr13Ni8Mo2Al steel at 1040 DEG C forging and molding, deflection is 50%, final forging temperature >=850 DEG C；Forging Afterwards, 0Cr13Ni8Mo2Al steel forgings are inserted in heating furnace, furnace cooling；
0Cr13Ni8Mo2Al steel forgings are heated to 927 DEG C of insulation 360min, the straight room temperature of water-cooled；Taking-up is inserted in icehouse, Transfer time≤120 second, icehouse temperature is subzero 50 DEG C, keeps 180min；540 DEG C of insulation 240min, sky are reheated to again It is cold.
Compared with prior art, beneficial effects of the present invention are as follows：
0Cr13Ni8Mo2Al precipitation-hardening stainless steels cold treatment method of the present invention, due to 0Cr13Ni8Mo2Al steel horses Family name's body converts started temperature Ms and finishing temperature Mf than relatively low, and the stainless steel of martensite can not be completely become at room temperature.This method It is used as intermediate treatment by using cold treatment, makes in cooling procedure, temperature can drops to below martensitic transformation started temperature Ms, So as to ensure that forging is fully converted to martensitic structure.
Specific embodiment
Implementing 0Cr13Ni8Mo2Al precipitation-hardening stainless steels cold treatment method of the present invention needs to provide Forge Heating The equipment such as stove, forcing press, manipulator, heat-treatment furnace, subzero 50 DEG C of icehouse.Its specific embodiment：
By 0Cr13Ni8Mo2Al steel at 1040 DEG C forging and molding, deflection is 50%, final forging temperature >=850 DEG C；Forging Afterwards, 0Cr13Ni8Mo2Al steel forgings are inserted in heating furnace, furnace cooling；
0Cr13Ni8Mo2Al steel forgings are heated to 927 DEG C of insulation 360min, the straight room temperature of water-cooled；Taking-up is inserted in icehouse, Transfer time≤120 second, icehouse temperature is subzero 50 DEG C, keeps 180min；540 DEG C of insulation 240min, sky are reheated to again It is cold.
