Advantages:

1. Good Mechanical Properties

Advanced Quenching and tempering ( QT) treatment makes the gears a good Mechanical properties so that it can adapt to various bad working environments.

 

2. High strength and good wear resistance

Gear surfaces can be carburized or nitrided to increase the hardness of the gears, increase wear resistance and extend service life.

 

3. Technical Support for installation guide and routine maintenance

Support customized drawing, sample processing, and can provide technical support and drawing design.

 

4. Quality control

Control of internal and surface defects in gears by UT, PT, and MT inspection.
