Stainless steel ball just how to heat treatment

Stainless steel is divided into austenitic stainless steel ball and martensite stainless steel ball, as well as ferritic stainless steel ball, different ways of steel ball processing is different also.


Austenitic stainless steel heat treatment of the purpose is to remove magnetic, because in the process of steel ball cold heading or grinding ball can produce magnetic work, and poor corrosion will edge, so by means of heat treatment can eliminate the magnetic, we usually heat treatment is to increase the electric oven temperature to 850 degrees, and then put into stainless steel ball, and then quickly into cold water, so that you can remove the magnetic.


Martensite stainless steel heat treatment of the purpose is to improve the hardness, but also increase the wear resistance of the stainless steel ball, so as to prolong the service life of steel ball. 420 stainless steel ball 2-5 mm heat treatment temperature at 1050 degrees, about 5 to 50 mm will be about 1080 degrees. Then stir in oil, and then becomes HRC48-55 hardness.


The ferritic stainless steel ball is out of the need for heat treatment.
