Product Description

 

What is QPQ? 

 

QPQ is a kind of heat treatment that can increase components’wear resistance and fatigue resistance. 

 

Ø   QPQ is short for "Quench-Polish-Quench".

 

Ø   QPQ technology is a new revolution technology in the field of metallurgy.

 

Ø   Technical Philosophy

 

     It permeates a variety of elements to metal surface in two different nature of salt bath.

 

Ø   Result After QPQ
 

     By QPQ treatment, the wear resistance and corrosion resistance of  component will be increased than conventional heat treatment.

 

 

Technical Parameter

 

Product Overviews

 

•     The second generation QPQ technology enable carbon compound layer thickness reach to more than 30μm.

 

•  The third generation of QPQ technology makes the thickness of carbon steel compound layer reach to 60 μmor even more by accelerating the formation of permeation layer by using electric current.
