How to solve the problem of surface decarburization of stainless steel welded pipe?

In people's production and life, stainless steel welded pipe plays a very important role. People find that with the growth of stainless steel welded pipe service life appearance will be decarbonization phenomenon, so how to avoid this problem?

To solve the problem of the appearance of decarburization of stainless steel welded pipe, the key in the heat treatment process. Need to take measures to change this kind of state. While the use of this technology is needed to avoid the lead dust pollution. A lot of stainless steel welded pipe product life and steel product appearance is related to the degree of decarburization. Because the oxygen decarburization and wire is simultaneously, so as long as the heat treatment process to make wire less contact with air can improve decarburization purpose. Decarburization layer overseas imports of stainless steel welded pipe is 0.04mm. The production process is: first molten lead groove steel austenitizing utility, will advance to lead liquid is heated to 871 DEG, stainless steel welded pipe after the molten lead, the successful implementation of austenite, and then entered the oil quenching tank, then enters the second melting lead groove tempering (482 C). Practice has proved that theUnited Statesspring steel wire enterprises using double lead groove oil quenching and tempering to dispose of valve spring steel wire, has obtained the ideal effect.
